When, in a social occasion, you stand behind someone and make a goofy distorted face to mock them without them knowing it and sort of try not to get caught, although getting caught is the best part.

When, in a blatently drunk-filled social gathering, one pre-loads his/her mouth with beer then purposely enters into an existing "conversation group" and does a slowly widening smile that allows all the uploaded beer to spill out of his/her mouth between the teeth (and down the shirt for maximum impact)as if they didn't know it was going to happen.
