Florida Orange Juice Surprise
Somewhat like a Cincinatti Surprise, except that you urinate into a balloon rather than defecate into a pillow case. You then throw the piss-filled balloon(like a water balloon) at someone and then watch as it bursts splattering the piss all over his/her face.
That mime was really boring and getting on everyone's nerves, so I've decided to pull the ol' Florida Orange Juice Surprise on him and watch as his white makeup gets totally ruined, his costume getting stained with piss, and everyone mocking, deriding, and laughing at him.
