Coprographia

Coprographia is involuntarily making vulgar writings or drawings.^[1] The word comes from the Greek κόπρος (kópros), meaning "feces", and γραφή (graphḗ), meaning "writing".^[2] Related terms are coprolalia, the involuntary usage of obscene and/or profane words,^[3] and copropraxia, the involuntary performance of obscene gestures.^[4] It should not be confused with the behavior of smearing actual feces, which is called scatolia.^[5]
