Coprographia

Not to be confused with Coprophagia.

Coprographia is involuntarily making vulgar writings or drawings.^[1] The word comes from the Greek κόπρος (kópros), meaning "feces", and γραφή (graphḗ), meaning "writing".^{[citation needed]} 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]
