scatology

From Ancient Greek σκῶρ (skôr, “excrement”) + -ology.

scatology (countable and uncountable, plural scatologies)

1. The scientific study or chemical analysis of faeces.
2. A filthy epithet.
   • 2008, Daniel Bernardi, The Persistence of Whiteness

     […] lingo of the streets with its spewed out scatologies and its anti-womanist rhetoric of "hoes and bitches" — all so evocative of life in the ghetto […]

3. (psychology, medicine) Interest in or obsession with faeces or other excrement.
   • 2015, Henry Powell and Howard Kushner, “Mozart at play: The limitations of attributing etiology of genius to Tourette syndrome and mental illness”, in Eckart Altenmüller, Stanley Finger, and François Boller, editors, Music, Neurology, and Neuroscience, page 290:

     Like James Joyce’s Leopold Bloom in the novel Ulysses (1922), Mozart seemed utterly comfortable with himself, bodily functions, and all. […] In our view Mozart’s so-called scatology is part of his culture and personality and, as we have argued, intimately connected with his creativity.

4. Literature, humor, or pornography featuring excrement or excreting.
   • 2010, Julie Cross, Humor in Contemporary Junior Literature, page 48:

     The move to out-and-out scatology in humorous texts for junior readers takes off in the later 1990s, following the overt scatological humor of ground-breaking ‘bum and poo’ picture books for younger readers, such as Holzwarth’s The Little Mole Who Knew It Was None of His Business (1998).
