A fetish revolving around the act of defecation. Similar to watersports. The term is used loosely to describe people who enjoy watching others shit; to sexual acts involving the use of feces.
A sub-genre called EFRO (erotic female relief observance) which involves the appreciation of female defecation is used to help differentiate the fetish.
Since early 2020, a toned-down variant of scat involves character doing enema using jelly-like substance has become increasingly popular.
