Coprophilia, also called scatophilia or scat, is the paraphilia involving sexual pleasure from feces. It is a deviant sexual act of defecating on one's partner's chest.
It has been referenced several times in Family Guy, including "A Picture's Worth a Thousand Bucks", "Mr. Saturday Knight", "Long John Peter", "German Guy", "Foreign Affairs", "Internal Affairs" and "The Fatman Always Rings Twice". In a bid to get around a direct reference, "Patriot Games" invents the word 'Clemond'.
