Coprographia Explained

Coprographia is involuntarily making vulgar writings or drawings.^[1] The word comes from the Greek Greek, Ancient (to 1453);: κόπρος, meaning "feces", and Greek, Ancient (to 1453);: γραφή, meaning "writing". Related terms are coprolalia, the involuntary usage of obscene and/or profane words,^[2] and copropraxia, the involuntary performance of obscene gestures.^[3] It should not be confused with the behavior of smearing actual feces, which is called scatolia.^[4]
