Coprophilia (from Greek κόπρος, kópros excrement and φιλία, philía liking, fondness), also called scatophilia or scat (Greek: σκατά, skatá feces), is the paraphilia involving sexual arousal and pleasure from feces. Research
In the Diagnostic and Statistical Manual of Mental Disorders (DSM), published by the American Psychiatric Association, it is classified under 302.89—Paraphilia NOS (Not Otherwise Specified) and has no diagnostic criteria other than a general statement about paraphilias that says "the diagnosis is made if the behavior, sexual urges, or fantasies cause clinically significant distress or impairment in social, occupational, or other important areas of functioning". Furthermore, the DSM-IV-TR notes, "Fantasies, behaviors, or objects are paraphilic only when they lead to clinically significant distress or impairment (e.g. are obligatory, result in sexual dysfunction, require participation of nonconsenting individuals, lead to legal complications, interfere with social relationships)". Although there may be no connection between coprophilia and sadomasochism (SM), the limited data on the former comes from studies of the latter. A 1999 study of 164 males in Finland from two SM clubs found that 18.2% had engaged in coprophilia; 3% as a sadist only, 6.1% as a masochist only, and 9.1% as both. In the study pool 18% of heterosexuals and 17% of homosexuals had tried coprophilia, showing no statistically significant difference between heterosexuals and homosexuals.
Sex-advice columnist Dan Savage dismissed the act as completely fictional. Brian Bouldrey in Dirty Words: A Literary Encyclopedia of Sex says the act is an urban legend. The New Partridge Dictionary of Slang and Unconventional English says, "This appears to have been contrived with the intention to provoke shock rather than actually as a practice, although, no doubt, some have or will experiment." Columnist Gustavo Arellano of ¡Ask a Mexican! contends the term evokes the stereotypical mustache of a Mexican. The term for the sex act entered British gay cant Polari in the 1960s.A Chicago sunroof is a fictional act, popularized in American crime drama series Better Call Saul, a spinoff of Breaking Bad. In the series, the titular character Jimmy McGill (Bob Odenkirk) defecates through an open sunroof as part of a revenge plan. As he (falsely) points out, “Its a real thing. I didnt make it up. Im not the first person to do it. Theres a name for it.” Series creator Peter Gould clarified in an interview that the "Chicago sunroof" is not real. See also
