Surprise, surprise: A brief overview of our recent papers on strange addictions and behaviours

Following my recent blogs where I outlined some of the papers that my colleagues and I have published on mindfulness, Internet addiction, gaming addiction, youth gambling, workaholism, exercise addiction, and sex addiction, here is a round-up of recent papers that my colleagues and I have published on strange and/or surprising addictions and behaviours.

Foster, A.C., Shorter, G.W. & Griffiths, M.D. (2015). Muscle Dysmorphia: Could it be classified as an Addiction to Body Image? Journal of Behavioral Addictions, 4, 1-5.

  • Background: Muscle dysmorphia (MD) describes a condition characterised by a misconstrued body image in which individuals who interpret their body size as both small or weak even though they may look normal or highly muscular. MD has been conceptualized as a type of body dysmorphic disorder, an eating disorder, and obsessive–compulsive disorder symptomatology. Method and aim: Through a review of the most salient literature on MD, this paper proposes an alternative classification of MD – the ‘Addiction to Body Image’ (ABI) model – using Griffiths (2005) addiction components model as the framework in which to define MD as an addiction. Results: It is argued the addictive activity in MD is the maintaining of body image via a number of different activities such as bodybuilding, exercise, eating certain foods, taking specific drugs (e.g., anabolic steroids), shopping for certain foods, food supplements, and the use or purchase of physical exercise accessories). In the ABI model, the perception of the positive effects on the self-body image is accounted for as a critical aspect of the MD condition (rather than addiction to exercise or certain types of eating disorder). Conclusions: Based on empirical evidence to date, it is proposed that MD could be re-classified as an addiction due to the individual continuing to engage in maintenance behaviours that may cause long-term harm.

Griffiths, M.D., Foster, A.C. & Shorter, G.W. (2015). Muscle dysmorphia as an addiction: A response to Nieuwoudt (2015) and Grant (2015). Journal of Behavioral Addictions, 4, 11-13.

  • Background: Following the publication of our paper ‘Muscle Dysmorphia: Could it be classified as an addiction to body image?’ in the Journal of Behavioral Addictions, two commentaries by Jon Grant and Johanna Nieuwoudt were published in response to our paper. Method: Using the ‘addiction components model’, our main contention is that muscle dysmorphia (MD) actually comprises a number of different actions and behaviors and that the actual addictive activity is the maintaining of body image via a number of different activities such as bodybuilding, exercise, eating certain foods, taking specific drugs (e.g., anabolic steroids), shopping for certain foods, food supplements, and purchase or use of physical exercise accessories. This paper briefly responds to these two commentaries. Results: While our hypothesized specifics relating to each addiction component sometimes lack empirical support (as noted explicitly by both Nieuwoudt and Grant), we still believe that our main thesis (that almost all the thoughts and behaviors of those with MD revolve around the maintenance of body image) is something that could be empirically tested in future research by those who already work in the area. Conclusions: We hope that the ‘Addiction to Body Image’ model we proposed provides a new framework for carrying out work in both empirical and clinical settings. The idea that MD could potentially be classed as an addiction cannot be negated on theoretical grounds as many people in the addiction field are turning their attention to research in new areas of behavioral addiction.

  • Dancing is a popular form of physical exercise and studies have show that dancing can decrease anxiety, increase self-esteem, and improve psychological wellbeing. The aim of the current study was to explore the motivational basis of recreational social dancing and develop a new psychometric instrument to assess dancing motivation. The sample comprised 447 salsa and/or ballroom dancers (68% female; mean age 32.8 years) who completed an online survey. Eight motivational factors were identified via exploratory factor analysis and comprise a new Dance Motivation Inventory: Fitness, Mood Enhancement, Intimacy, Socialising, Trance, Mastery, Self-confidence and Escapism. Mood Enhancement was the strongest motivational factor for both males and females, although motives differed according to gender. Dancing intensity was predicted by three motivational factors: Mood Enhancement, Socialising, and Escapism. The eight dimensions identified cover possible motives for social recreational dancing, and the DMI proved to be a suitable measurement tool to assess these motives. The explored motives such as Mood Enhancement, Socialising and Escapism appear to be similar to those identified in other forms of behaviour such as drinking alcohol, exercise, gambling, and gaming.

  • Although recreational dancing is associated with increased physical and psychological well-being, little is known about the harmful effects of excessive dancing. The aim of the present study was to explore the psychopathological factors associated with dance addiction. The sample comprised 447 salsa and ballroom dancers (68% female, mean age: 32.8 years) who danced recreationally at least once a week. The Exercise Addiction Inventory (Terry, Szabo, & Griffiths, 2004) was adapted for dance (Dance Addiction Inventory, DAI). Motivation, general mental health (BSI-GSI, and Mental Health Continuum), borderline personality disorder, eating disorder symptoms, and dance motives were also assessed. Five latent classes were explored based on addiction symptoms with 11% of participants belonging to the most problematic class. DAI was positively associated with psychiatric distress, borderline personality and eating disorder symptoms. Hierarchical linear regression model indicated that Intensity (ß=0.22), borderline (ß=0.08), eating disorder (ß=0.11) symptoms, as well as Escapism (ß=0.47) and Mood Enhancement (ß=0.15) (as motivational factors) together explained 42% of DAI scores. Dance addiction as assessed with the Dance Addiction Inventory is associated with indicators of mild psychopathology and therefore warrants further research.


Greenhill, R. & Griffiths, M.D. (2015). Compassion, dominance/submission, and curled lips: A thematic analysis of dacryphilic experience. International Journal of Sexual Health, 27, 337-350.

  • Objectives: Dacryphilia is a non-normative sexual interest that involves enjoyment or arousal from tears and crying, and to date has never been researched empirically. The present study set out to discover the different interests within dacryphilia and explore the range of dacryphilic experience. Methods: A set of online interviews were carried out with individuals with dacryphilic preferences and interests (six females and two males) from four countries. The data were analyzed for semantic and latent themes using thematic analysis. Results: The respondents’ statements focused attention on three distinct areas that may be relevant to the experience of dacryphilia: (i) compassion; (ii) dominance/submission; and (iii) curled-lips. The data provided detailed descriptions of features within all three interests, which are discussed in relation to previous quantitative and qualitative research within emotional crying and tears, and the general area of non-normative sexual interests. Conclusions: The study suggests new directions for potential research both within dacryphilia and with regard to other non-normative sexual interests.

  • Aims: Recent research has suggested that for some individuals, educational studying may become compulsive and excessive and lead to ‘study addiction’. The present study conceptualized and assessed study addiction within the framework of workaholism, defining it as compulsive over-involvement in studying that interferes with functioning in other domains and that is detrimental for individuals and/or their environment. Methods: The Bergen Study Addiction Scale (BStAS) was tested — reflecting seven core addiction symptoms (salience, mood modification, tolerance, withdrawal, conflict, relapse, and problems) — related to studying. The scale was administered via a cross-sectional survey distributed to Norwegian (n = 218) and Polish (n = 993) students with additional questions concerning demographic variables, study-related variables, health, and personality. Results: A one-factor solution had acceptable fit with the data in both samples and the scale demonstrated good reliability. Scores on BStAS converged with scores on learning engagement. Study addiction (BStAS) was significantly related to specific aspects of studying (longer learning time, lower academic performance), personality traits (higher neuroticism and conscientiousness, lower extroversion), and negative health-related factors (impaired general health, decreased quality of life and sleep quality, higher perceived stress). Conclusions: It is concluded that BStAS has good psychometric properties, making it a promising tool in the assessment of study addiction. Study addiction is related in predictable ways to personality and health variables, as predicted from contemporary workaholism theory and research.

  • Background and aims: ‘Study addiction’ has recently been conceptualized as a behavioral addiction and defined within the framework of work addiction.  Using a newly developed measure to assess this construct, the Bergen Study Addiction Scale (BStAS), the present study examined the one-year stability of study addiction and factors related to changes in this construct over time, and is the first longitudinal investigation of study addiction thus far. Methods: The BStAS and the Ten Item Personality Inventory (TIPI) were administered online together with questions concerning demographics and study-related variables in two waves. In Wave 1, a total of 2,559 students in Norway and 2,177 students in Poland participated. A year later, in Wave 2, 1,133 Norwegians and 794 Polish who were still students completed the survey. Results: The test-retest reliability coefficients for the BStAS revealed that the scores were relatively stable over time. In Norway scores on the BStAS were higher in Wave 2 than in Wave 1, while in Poland the reverse pattern was observed. Learning time outside classes at Wave 1 was positively related to escalation of study addiction symptoms over time in both samples. Being female and scoring higher on neuroticism were related to an increase in study addiction in the Norwegian sample only. Conclusion: Study addiction appears to be temporally stable, and the amount of learning time spent outside classes predicts changes in study addiction one year later.

Whirled piece: Dancing as an addiction

In previous blogs I have examined various (admittedly extreme) aspects of dancing including people that are sexually aroused by dancing (choreophilia), dancing as a form of frottuerism, people that are addicted to dancing (in this case, the Argentine tango), and people who have developed medical complaints as a result of dancing (‘breaker’s neck’ caused by break dancing). However, over the last few months I have been a co-author on two dance-related research papers with my research colleagues in Hungary (led by Aniko Maraz). The first one (published in the journal PLoS ONE) was about the development and psychometric validation of the ‘Dancing Motives Inventory’ (DMI). The second one (also published in PLoS ONE) was a study of dance addiction (and which I will describe in more detail below).

I’m sure many of you reading this will think that dancing is a somewhat trivial area to be carrying out scientific research. However, research has shown that dancing can have substantial benefits for physical and mental health such as decreased depression and anxiety, and increased physical and psychological wellbeing. After we developed the DMI, we realised that very little known about the psychological underpinnings of excessive dancing, and whether in extreme cases, dancing could be classed as an addictive behaviour. Given the lack of empirical research in dance addiction, we conceptualized dance addiction to be akin to exercise addiction. For example, a study published in the journal Perceptual and Motor Skills led by Dr. Edgar Pierce reported that dancers scored higher on the Exercise Addiction Scale compared to endurance and non-endurance athletes. Added to this, both exercise and dancing require stamina and physical fitness, and for this reason, dance is often classified as a form of exercise.

Over the last 20 years I have published many papers on exercise addiction (see ‘Further reading’ below) so there is no reason why dance addiction couldn’t theoretically exist (in fact, it could be argued that dance addiction – if it exists – is a sub-type of exercise addiction). There are also a handful of studies that have examined excessive dancing and whether it can be addictive to a small minority. A study by Edgar Pierce and Myra Daleng (again in Perceptual and Motor Skills) conducted a study with 10 elite ballet dancers and found that dancers rated thinner bodies as ideal and significantly more desirable than their actual body image despite being in the ‘ideal’ BMI range. The study also found that dancers often continue to dance despite discomfort, “because of the embedded subculture in dance that embraces injury, pain, and tolerance”. In a more recent study in the Journal of Behavioral Addictions (and which I reported at length in a previous blog), Dr. Remi Targhetta and colleagues assessed addiction to the Argentine tango. They found that almost half of their participants (45%) met the DSM-IV criteria of abuse, although a substantially lower prevalence rate (7%) was found when using more conservative criteria.

In our recently published study, we proposed that excessive social dancing would be associated with detriments to mental health. More specifically, we aimed to (i) identify subgroups of dancers regarding addiction tendencies, (ii) explore which factors account for the elevated risk of dance addiction, and (iii) explore the motivations underlying excessive dancing.

Our sample included 447 salsa and ballroom dancers (32% male and 68% female, with an average age of 33 years) who danced recreationally at least once a week. To assess ‘dance addiction’ we created the ‘Dance Addiction Inventory’ modified from the Exercise Addiction Inventory (that I co-developed back in 2004) in which we simply replaced the word ‘exercise’ with the word ‘dance’. We also assessed the dancers’ general mental health, borderline personality disorder, eating disorder symptoms, and dance motives.

As far as we are aware, our study is the first to explore the psychopathology and motivation behind dance addiction. Based on my criteria of addiction, five distinct types of dancers were identified. Only two of these types danced excessively. About one-quarter of our sample reported high values on all criteria of addiction but they reported no conflict with the social environment. However, 11% of dancers (and what we termed the ‘high risk’ group) scored high on all addiction symptoms and experienced conflict in their life as a consequence of their excessive dancing.

Our study also found that dance addiction was associated with mild psychopathology, especially with elevated number of eating disorder symptoms and (to a lesser extent) borderline personality traits (something which has also been found in research examining exercise addiction). Perhaps unsurprisingly, escapism (and to a lesser extent mood enhancement) was an especially strong indicator of dance addiction. I say ‘unsurprisingly’ because escapism has already been much reported in other types of behavioural addiction such as gambling and video gaming (including a lot of my own research). Here, escapism as a motivational factor refers to dancing in order to avoid feeling empty or as a mechanism to deal with everyday problems. Based on our findings, we believe that to a minority of individuals appear to be addicted to dancing and that it may be being used be a maladaptive coping mechanism.

Based on what we know in the exercise addiction literature, we proposed that future studies should also assess whether eating disorder is primary or secondary to dance addiction (i.e., whether the purpose of excessive dancing is weight-control and/or the motivation to perform leads to disturbances in eating patterns). I should also point out that although we found that distress was correlated with dance addiction, the association disappeared when other measures were added to the regression model. This may indicate that distress is not directly associated with problematic dancing and that it may arise from other problematic factors such as having an eating disorder.

Given the lack of research in the field, other studies are needed to confirm or refute the findings of our study. Given that dancing is a social activity, social conflicts may not arise when the person has only fellow dancers as partners or friends – therefore, the risky behaviour may remain somewhat hidden. Another question that could be examined is whether there is any difference between amateur and professional dancers in terms of addiction tendency (although among professional dancers there may be a debate about whether their behaviour is dancing addiction or ‘workaholism’). Also, we don’t know whether our findings can be extended to other dance genres (as we only surveyed ballroom and salsa dancers)

I would just like to end by saying that dancing is very clearly a healthy activity for the majority of individuals. However, our study does seem to suggest that excessive dancing may have problematic and/or harmful effects for a small minority. Although we couldn’t establish causality, dance addiction appears to have the potential to be associated with mild psychopathology.

Coining it in: Neologisms and ‘New Syndrome’ Syndrome

One of things I am very proud of in my academic career is the coining of the term ‘technological addiction’ back in 1995 (an umbrella term that I invented to describe a number of different person-machine addictions including slot machine addictions, video game addiction, television addiction, etc.). I’m also proud of coining the term ‘aca-media’ (relating to academics like myself that use the media to disseminate our research). A neologism (i.e., the name for a newly coined term) is often (according to Wikipedia) directly attributable to a specific event, person, publication, or period.

In the 1980s and early 1990s, there seemed to be a real upsurge is the naming of ‘new syndromes’ in the medical literature including many relating to excessive use of technology (such as ‘Space Invader’s Wrist’) and other leisure activities (such as ‘Cuber’s Thumb’ relating to excessive use of the Rubik’s Cube) – both of which made their appearance in 1981 issues of the New England Journal of Medicine. Other videogame medical complaints include ‘Pseudovideoma’ (in a 1984 issue of the Journal of Hand Surgery), ‘Pac-Man Phalanx’ (in a 1983 issue of Arthritis and Rheumatism) and ‘Joystick Digit’ (in a 1987 issue of the Journal of the American Medical Association). Another videogame-related medical complaint (in this case an infection), was reported in a 1987 issue of the Western Journal of Medicine by Dr. G.B. Soe and colleagues:

“We wish to focus WJM readers’ attention on another complication associated with video games-one that originally presented as an “infected spider bite. A 17-year-old right-handed boy noted progressive swelling and redness of his left hand seven days before admission. Two days before admission he was given penicillin intramuscularly and oral cephalexin to take at home. The swelling did not subside and the hand became very painful, so he came to the medical center for treatment. On admission his mother reported that she had seen many spiders around the house with a violin pattern on their backs, and that her son had probably been bitten by a spider…After seven days of parenteral antibiotic therapy, the edema, erythema and fever had disappeared and the patient was discharged home. Further questioning revealed that the young man was spending almost all of his time playing his favorite video game, which involved a fighting kung fu character. The patient used his left hand in manipulating a ball-shaped joystick to move the figure up, down, left and right, and his right in operating buttons to kick and jab. Extensive use of the joystick resulted in blisters on his left palm. He rubbed the blisters off, and an infection resulted that progressed to abscess formation. Neuromuscular complications of video games (‘pseudovideoma’, ‘Pac-Man phalanx’, ‘firing-finger syndrome’ and ‘Space Invaders wrist’) have been reported, as well as video game-induced seizures, but we have not come across any reports of an infectious complication of video games. Perhaps video game players should wear gloves to protect their palms, similar to ones worn by golfers and baseball players, who also need to get a firm grip on their respective sticks”.

Another one that I’d never heard of is ‘Nurd Knuckles’ coined by Dr. J.B. Martin in the Canadian Medical Association Journal in 1982:

“I wish to describe a case of painful knuckles associated with the use and manipulation of a new, allegedly therapeutic product, a Nurd. A Nurd is a head 10 cm across with a smiling face and large ears, reminiscent of the character Yoda of ‘Star Wars’. It is made of malleable material that can be stretched, twisted or deformed in any direction, yet with release of tension quickly resumes its original shape without a trace of distortion. A 32-year-old public school teacher presented with painful knuckles of his right hand. His students, perhaps feeling that their teacher was under increased stress during the marking of exams, had given him a Nurd for Christmas, and during a particularly trying day he had found occasion to use it. He repeatedly stretched its ears and twisted its neck without ill effect; however, on punching it he suffered sharp pain of his fourth and fifth metacarpophalangeal joints. On examination the joints were found to be reddened, with point tenderness over the fifth metacarpal head; there was no evidence of deformity. He was advised to stop beating his Nurd, and the pain subsided. While the Nurd is very plastic, yielding to the linear tension of stretching and twisting, it is very resistant to compression. Punching a Nurd does not cause the surface to give way, and, since the force of the blow is returned to the fist, it is conceivable that a fracture might result. Therefore, although stretching and twisting Nurds does not cause any harm, users should be cautioned against punching their Nurd. The Nurd is advertised as being a ‘punchable, stretchable, pushable and likeable alternative to tension, migraine headaches, drug abuse, alcoholism and manic depression’, but these claims are unsubstantiated. A MEDLINE search of the medical literature shows that no retrospective or prospective case control studies or controlled double blind crossover studies have been undertaken. Before the clinical efficacy of the Nurd can be taken seriously in the treatment of this broad spectrum of disease, full clinical trials must be completed. Subjects entering into trials must, however, be duly informed of the hazards of punching Nurds”.

Another one that caught my attention was a new affliction (‘Breaker’s Neck’) caused by the craze of ‘break dancing’ reported by Dr. Bertha Ramirez and her colleagues in a 1984 issue of the Journal of the American Medical Association. (The reason why I say it caught my eye is that I am currently involved in some research on ‘dancing addiction’ with some of my Hungarian colleagues and we have just had a new paper accepted in the journal PLoS ONE concerning the development of our ‘Dancing Motives Inventory’ – see ‘Further Reading’ below).

To be added to the rapidly growing list of socially acquired injuries, we report a case of traumatic cervical subluxation caused by a new dance technique. This technique, labeled ‘breaking’ by its devotees, involves a modified head stand, in which the dancer, using his arms and hands for balance, spins rapidly on his head, neck, or shoulders to the rhythm of disco music. He then lowers his body to the floor and performs a series of rotational motions using his arms as a fulcrum…A 15-year-old boy was seen in our pediatric emergency room complaining that, on awakening two days previously, he felt a ‘snap’ in his neck, followed by persistent neck stiffness. He reported having ‘danced on his head’ the night prior to this incident. On physical examination, his head was tilted to the left with an inability to flex”.

Engaging in excessive sporting activity has given rise to a number of medical syndromes. One such consequence is ‘Rower’s Rump’ reported by Drs. K Tomecki and J. Mikesell in a 1987 issue of the Journal of the American Academy of Dermatology. In a previous blog I examined addiction to cycling. In the 1980s there were many medical complaints reported as a result of excessive cycling. One such complaint (given the name of ‘Bicycling nipples’) was highlighted by Dr. B. Powell in a 1983 issue of the Journal of the American Medical Association:

“Bicyclists are likely to suffer from a number of maladies, including dysuria, numb penises, and more. During cool or cold weather, another problem, bicyclist’s nipples, may occur. This condition is similar to jogger’s nipples, but it is primarily a thermal injury instead of an irritation secondary to friction, as with the jogger’s complaint. Often the rider is out in the cold weather for some time, and his or her undershirt, jersey, and jacket can become moist from perspiration. Evaporation and the chill of the wind lower the temperature of the nipples. They get downright cold, and they hurt. The pain continues after the ride is over. Indeed, it can continue for several days. The nipples are sore, sensitive to both temperature change and touch”.

After reading this I found out that Dr. Fred Levit had reported a case of ‘Jogger’s Nipples’ in a 1977 issue of the New England Journal of Medicine. All of these related nipple conditions are all examples of fissure of the nipple as they are all caused by friction resulting in soreness, dryness or irritation to, or bleeding of, one or both nipples. The Wikipedia entry also notes that “the condition is also experienced by women who breastfeed, and by surfers who do not wear rash guards”. The article also noted that:

“Jogger’s nipple is caused by friction from the repeated rubbing of a t-shirt or other upper body clothing against the nipples during a prolonged period of exercise. The condition is suffered mainly by runners. Long-distance runners are especially prone, because they are exposed to the friction on the nipple for the greatest period of time. However, it is not only suffered by athletes; the inside of a badge, a logo on normal items of clothing, or breastfeeding can also cause the friction which results in this condition”.

Outside of the leisure sphere, there were two case study reports of ‘Diaper Doer’s Hand’ in a 1987 issue of the journal Clinical Rehabilitation by Dr. J.L. Cosgrove and colleagues:

“Three cases of stenosing tenosynovitis occurred three to six months postpartum. Childcare activities aggravated the symptoms of pain and swelling in both patients. In two cases, a specific method of carrying the child was implicated as the mechanism of injury. Although there was no evidence of generalized inflammatory arthritis, all patients had very low positive titres of anti-nuclear antibodies. While it is likely that tenosynovitis was caused by mechanical factors, the possibility of increased susceptibility to inflammatory disease in the postpartum period cannot be discounted. The patients were successfully treated with a low temperature plastic splint, superficial heat and gentle mobilization”.

All of these new syndromes lead to why I put this article together in the first place. I found this letter in the British Medical Journal by Dr. E.P. Hoare entitled ‘New Syndrome Syndrome’ that I found both funny and poignant:

“Your readers will be familiar with tennis elbow, brazier’s ague, and soap packer’s jig not to mention Achilles’ heel. More recently we have heard of Space Invader’s wrist, jogger’s nipples, and the ultimate futility of Cuber’s thumb. May I point out another occupational disease which I have noticed among patrons of the reading room medical journal correspondence column reader’s neck or, more succinctly, the new syndrome syndrome. Symptoms usually begin with muscular contraction of the eyebrows, hyperventilation, and involuntary utterances, which in severe cases can lead to coprolalia. These may be followed by drowsiness, disorientation, hysterical amblyopia, and double vision (of the deja vu variety). If untreated the condition can result in a chronic pain in the neck. Treatment is 200 ml of gin and tonic stat by mouth and complete rest; music can also be helpful. The long-term prognosis is poor, however, unless journal editors can be persuaded to ban further reports of occupational afflictions or at least print a health warning at the head of their correspondence columns”.

Blame it on the boogie: A brief look at dancing as frotteurism

In a previous blogs I have examined both choreophilia (sexual arousal from dancing) and frotteurism (sexual arousal (sexual arousal from non-consensually rubbing up against other people). However, while researching these previous blogs I came across a number of academic papers on ‘dancing frottuerism’. For instance, in a book chapter on frotteurism by Dr. Richard Krueger and Dr. Meg Kaplan, they outlined four case studies of frotteurs in treatment, one of which was a 58-year old male that had engaged in various types of frotteuristic behaviour over a 40-year period (estimated 20,000 acts of frotteurism). This included “dirty dancing” where he would go to nightclubs and deliberately rub himself up against women while dancing with them. He estimated that he engaged in this type of frotteuristic behaviour on approximately 100 nights of the year (compared to other frotteuristic behaviour such as rubbing himself against women on buses and in train subways approximately 200 days a year).

In a short online article concerning frotteurism on the Anxiety Zone website, the term ‘dry humping’ (aka ‘grinding’) is viewed as a form of modern dancing style. The same article also notes that frotteurism may not always be non-consensual:

“Frotteurism carries a connotation of ‘anonymous and discreet rubbing’ in a public place – like on a crowded train. The contact may be mutual or a one-way perpetration…As with most other sexual practices, frottage with a non-consenting person is regarded as a form of sexual assault in most jurisdictions…Frot is a term used among homosexual men to refer to penis to penis rubbing in a conventional private context. It is also known as ‘phrot’, ‘swordfighting’, ‘cockrub’, ‘penis fencing’, ‘bumping dicks’, ‘frication’ and ‘the Princeton rub’. Advocates of this practice represent it as a safer and more erotic alternative to anal sex. Two people engaging in clothed frottage in a manner that simulates intercourse is known in the vernacular as ‘dry humping’. A modern dancing style which involves partners rubbing their clothed bodies on one another is called grinding”

The online Encyclopedia Dramatica also appears to concur, and notes in its article on frotteurism that sometimes, bump and grind dancing in clubs is also thought of as being frottage”. Frotteurism in the form of dancing appears to be an accepted part of leisure life in the Caribbean. According to a short online article (‘Frottage and Frotteurism in the Caribbean’), dancing frotteurism occurs when couples are dancing (“typically with the man behind the woman. It is something like freak dancing in the US except that nobody is scandalised by it and it is not restricted to teenagers. In Jamaica there are dance events called ‘rubs’ where pelvic thrusting is meant to happen”).

However, some academics do not see this Caribbean practice as socially acceptable. For instance, Dr. Hari Maharajh published a 2010 book chapter entitled ‘Dancing frotteurism or rubbing at the Carnival celebrations in Trinidad’. (Although this appears to be based on an earlier paper published in a 2007 issue of the Journal of Chinese Clinical Medicine). Dr. Maharajh noted that Trinidad and Tobago had been influenced by a variety of cultures that finds its greatest expression during the Carnival season. More specifically, it was reported that:

“During this [Carnival time] a local dance form of wining with suggestible sexual movements is pervasive. It is associated with distortions of normal courtship behavior with paraphilic disturbances. In a case presentation, a young male is presented showing paraphilic disturbances touching, holding, rubbing and coercive sex. This behavior of frotteurism and other paraphilias are common occurrences at carnival in Trinidad and Tobago and are considered to be cultural normative practices”.

The Carnival occurs on many Caribbean islands (not just Trinidad and Tobago) and is celebrated just before Lent. Dr. Maharajh’s case study attempted to identify a number of sexual paraphilias such as “toucherism, frotteurism and preferential rape” during the Trinidad and Tobago Carnival celebration and then looked at some of the legal ramifications of such behaviour. Similar observations were also made in a 2013 paper by Annette George et Darlington Richards in the online journal Études Caribéennes.They noted that two specific behaviors continue to be of concern during the Carnival: (i) the high levels of alcohol consumption during the Carnival’s festivities and, (ii) the erotic dancing and wining expressed by the Carnival participants. They wrote that:

“[In addition to the amount of alcohol consumed during the Carnival, the] second major concern of the celebrations is the dancing or wining. Wining, a term used to describe sensuous pelvic gyrations of the hips and waist, is considered to be suggestive and sexually stimulating not only to the revelers but also to on-lookers (Maharajh & Konings, 2007; Miller, 1991). It is also considered expressions of enjoyment, happiness and freedom…Similarly, Miller (1991) reports that wining between men and women during Carnival, is clearly a sexual expression that encourages rape”.

Maharajh also concurred that excessive alcohol consumption is a key feature of the Carnival and that it is seen as a “time to free up, break away and get on bad” including promiscuity and other “immoral and inexcusable” behaviours. George and Darlington argue that for these reasons, the Trinidadians as a group have a ‘carnival mentality’ that equates to a never-ending all year-round ‘party mentality’. Maharajh claims that in Trinidad, sex is a “comparative performance for both men and women”, and that an activity such as wining “is viewed as either a form of ‘virtual sex’ or as an expression of sexuality”.  Citing the work of Dr. C.L. Green (2007), George and Darlington note that the “Carnival is nothing more than an orgy of sexuality and hedonism appealing to the fetishistic fantasies of the potential tourist”, George and Darlington then go on to claim that:

“This contextual, if tantalizing environment for the ‘carnival spirit’ for the locals have an equal, if not more, tantalizing allure for the tourists. The prevailing environment of social, and cultural permissiveness and intermingling, allows for the indulgent tourist to be part of the rascality and the attendant exposure”.

As a backdrop to any debate concerning whether sexual dancing is a legitimate form of frotteurism, it is clear that appropriate sexual behaviours depend on the surrounding context (cultural and/or social) including the time and the place of where the behaviour occurs. Some sexual behaviours that may be unacceptable under most circumstances (e.g., being nude in public, sexual contact between individual dancers) appears as though they are encouraged during celebrations like Mardi Gras or the Carnival.
