Coprophilia (from Greek κόπρος, kópros - excrement and φιλία, filía - liking, fondness), also called scat, is the paraphilia involving sexual pleasure from feces.. In the Diagnostic and Statistical Manual of the American Psychiatric Association (DSM-IV-TR), it is classified under 302.9 Paraphilia 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)."
The Cleveland steamer is a form of coprophilia, where a person defecates on a partner's chest. The term received news attention through its use in a U.S. Congress staff hoax email and being addressed by the United States Federal Communications Commission.
The Hot Carl (or alternately Hot Karl) is another form of coprophilia, whereby a person defecates onto or into a partner's mouth. Parties unwilling to taste or consume the feces itself can opt for a strip of cellophane to be placed over their mouth, allowing the warm sensation to still be present without any direct contact with the skin or linings of the mouth.
