Coprographia
Coprographia is involuntarily making vulgar writings or drawings. Coprographia comes from the Greek κόπρος (kópros), meaning "feces", and γραφή (graphḗ), meaning "writing".
Related terms are coprolalia, the involuntary usage of scatological words, and copropraxia, the involuntary performance of obscene gestures.
Though unsupported allegations of coprography have been made toward Comcast, an American cable company operating under the name Xfinity, particularly with regard to their contracts involving data caps, this should not be confused with Brian L. Roberts, CEO of Comcast and well-known practitioner of coprophagy.
