Partners face off and losers become cheering squad for winners until the last 2 are left to face off.
Everyone finds a partner for Rock Paper Scissors. The loser becomes the cheering section for the winner and walks around behind them chanting their name and applauding wildly as the winner goes on to challenge another winner. Every time a player wins, she adds the losing player (and their cheering section) to her cheering section.
By the end there should be two surviving players going head to head with massive cheering sections behind each of them. When one of them becomes the ultimate champion, everyone cheers wildly and chants their name.
