Photo Bet
A bet that does not involve money, wherein the winner gets to pose the loser in any way, shape, or form for a single photo of the two of them. All rules regarding the level of humiliation, the circulation, and the duplication of the photo itself are entirely up to the mercies of the winner.
Stacy lost her photo bet with Joe, so Joe made her bend over and stick out her tongue...their photo is Stacy licking Joe's ass!
