Scatologic is an adjective that is commonly used to describe anything related to excrement or feces. In scientific or medical contexts, other synonyms include fecal, coprolithic, or defaecatory. In more informal settings, words like dirty, filthy, or foul may be used to refer to things related to excrement. If a person wishes to be more tactful, they may use euphemisms like waste materials, excreta, or even animal droppings. Other synonyms may include vulgar, offensive, or indecent, depending on how the word is being used. Ultimately, the synonym chosen will depend on the situation and audience, as well as the speaker's personal preferences for vocabulary.
