Up dude

Stuck up and snobby; arrogant. Someone who has jumped so far up their own ass, though not necessarily a male, that they become intolerable. Inspired by ponytails: People who wear / have them tend to act better than others.

"That girl is so up dude."

"Your boyfriend is hot but he's is too too fucking up dude."

"Man, chill out, don't be so up dude!"
