An incompetent hero whose splayed out state of disarray (generated in an attempt to quest) conjures the image of a salad.
Look at all the scarabs he's left behind! Nub salad!
When a nub gets owned by multiple nubs, they become a nub salad.
When you get owned at a game, and its not even close, and the other player is a pats fan
When you play a game of blitz and the opposite player is a pats fan, and you destroy them with the jets, you have the rights to call them a nub salad or just the blitz bitch.
