A gamble to decide whether a loss or debt from a previous bet should be doubled or canceled.
Person A wins $5 off of Person B. Person B says "Double or nothing". Person B wins the second bet and the preexisting loss is canceled and no one receives money. If Person A wins the second then he receives double the amount of the first bet.
