Trashmouth, also known as Richie Tozier, is a boy from the book IT, and the movie IT (1990 & 2017)

A cultural and aesthetic mind-state that prioritizes making money, even as an “underground” or “radical” creator. The work isn’t made for money, but it’s the money that matters the most.

Someone who just can’t keep their mouth shut. Usually a big fan of profanity and non-pc language.

Snaggletoothed, whorish looking smile. Typically a trashmouth girl will purse her lips in a tight, strange manner to hide her fucked up teeth. See country singer Jewel. Note that not every trashmouth girl is a cock gobbler - but most of them are.
