Ass nut lamb gravy is a synonym for a greasy nut you bust in someones ass that has the same consistency as some cold gravy. It's usually used in some
weird kinky shit where
people like to be embarrassed sexually, or be talked down to like some sort of
joke.
Could also be used in a sarcastic tone, but personally, I dont think ass nut lamb gravy is a joking matter. It's very serious.
"Take my ass nut lamb gravy you disgusting
thanksgiving whore"
"I'd be careful
buddy, dont wanna catch some ass nut lamb gravy by accident"
"You smell and look like a
bowl of rotten ass nut lamb gravy, put on some deodorant"
