Vomit Fetish

Emetophilia, also called emetolagnia, is a sexual interest in the act of vomiting or in vomit itself (whether one's own, a partner's, or the sight, sound, or smell of another person being sick. It is grouped with the excretory bodily-function interests and is documented mainly in reference catalogues of paraphilias and in small online communities rather than in a dedicated research literature. This article covers the term's origins, how the interest is understood clinically, its psychology, its rarity, and) most importantly: its substantial health and consent considerations. The treatment here is strictly descriptive, with no instructional content whatsoever.

History & origins

Terminology & clinical lineage

The precise coinage of emetophilia is not well documented, and it is best regarded as a modern, finer-grained label rather than a classical clinical term. Its roots are clear: Greek emesis / emetikos ("vomiting; that which induces vomiting") combined with -philia ("love of, affinity for"), with the variant emetolagnia using -lagnia ("lust"). The interest belongs to the broad nineteenth-century project of naming sexual variations (exemplified by Richard von Krafft-Ebing's Psychopathia Sexualis (1886), which established the practice of cataloguing such interests with Latin and Greek labels) but emetophilia itself is a later addition to that lineage and was not a term Krafft-Ebing used. Today it survives chiefly in descriptive references such as the list of paraphilias rather than in primary clinical research.

The "Roman shower" misnomer

The popular epithet "Roman shower", slang for being vomited on in a sexual context, is a modern coinage that alludes to the belief that ancient Romans habitually induced vomiting at feasts so they could keep eating. Historians regard this as a myth: a vomitorium was in fact an amphitheatre passage that "spewed" crowds out to their seats, not a purging room, and the gluttony trope appears to be a 19th- and 20th-century misreading of satirical Roman sources. The term therefore reflects cultural folklore rather than any documented historical practice.

Diagnostic status

In contemporary diagnostic systems neither the DSM-5-TR nor the ICD-11 lists emetophilia as a discrete disorder. Like most uncommon paraphilias, it would be captured only under a broad "other specified paraphilic disorder" heading, and only where it causes the person marked distress or impairment, or where it involves a non-consenting party. A consensual private interest that causes no harm is not, in itself, a clinical diagnosis.

In practice

Reported manifestations are uncommon and, in described accounts, are typically situated within established consensual contexts. The focus may attach to the act of being sick, to associated sensations, to the visceral sight or sound, or to dynamics of vulnerability and loss of control: the last linking it conceptually to humiliation and power-exchange play. Consistent with the educational and non-explicit purpose of this entry, no descriptions of technique are provided.

Psychology

Proposed explanatory frameworks are drawn from general models of paraphilic interest rather than from dedicated study of emetophilia, which has essentially none. They include associative learning (an arousal response conditioned to an unusual cue), the eroticisation of taboo and of loss of bodily control, and links to humiliation or dominance-and-submission dynamics that recur across the excretory interests. Individually low disgust sensitivity is also cited as a plausible contributing trait, since interest in body-fluid stimuli runs counter to the strong disgust response most people have. No specific cause is established, and the evidence base is thin and largely inferential.

Prevalence & culture

The interest has very low prevalence and little academic study beyond cataloguing, so any estimate is highly uncertain and leans on niche community size. The best available proxy is the broader finding from Scorolli et al. (2007), a large analysis of online fetish communities, that body-fluid and excretory interests collectively form only a small share of fetishes overall, consistent with emetophilia being a rare niche within that already-small group. Community presence on platforms such as FetLife is correspondingly modest. Mainstream cultural visibility is minimal and largely limited to the interest's deployment as a shock or taboo reference.

Safety, consent & law

Deliberately inducing vomiting carries real and serious health risks. Repeated self-induced vomiting produces the same medical harms seen in bulimia nervosa: erosion of tooth enamel by stomach acid, tears of the esophagus, electrolyte and fluid imbalance, and the danger of choking or aspiration. For these reasons the interest is flagged extreme-risk. Any expression requires fully informed adult consent and caution, and recurrent self-induced vomiting can additionally signal an eating disorder that warrants medical attention. The interest would warrant clinical attention where it causes distress or impairment, and it is illegal where it involves a non-consenting person, a minor, or coercion.
