Ass Genius 

A person who has diluted themselves into believing that the ideas created in and voiced directly from their ass, are pure genius.

Woman: So you're trying to tell me the inflatable party sheep was just a gag gift, and it came with the KY smears and pubic hair already stuck to it?

Man: Yes! It's really quite remarkable, isn't it?

Woman: You are a consummate ass-talker.

Man: Oh, come on - that story was brilliant! It's like I'm an Ass Genius or something!
