muk
A complete and utter moron. One who constantly blacks out, forgets important things and subsequently argues their point to be valid when everyone in the room knows it's not. A muk also enjoys looking at the sky while speaking.
Sam: Bro, let's go eat at Bento

Sam: It's cool, he's too busy NOT smoking pot tonight!
