Somebody holding a deck of cards will offer to play "Tidy Up" and the gullible unsuspecting victim, thinking that this is a card game, will take up the offer. Then the person with the cards will throw the cards all over the floor and then order the victim to "tidy up". The game can also similarly be titled "Clean up", "Janitor", "Cleaner", or "Vaccuum".
Ross: "Wanna play Tidy Up?"
Deb: "How d'you play that?"
Ross: "I'll show you"
Ross throws the cards in his hand over the floor
Ross: "Tidy Up!"
