odds on 

Sort of a dare in game form. One person calls "odds on" the other performing some unpleasant or undesirable task. The other person then sets the odds by giving a number. One will then count down from 3, and both say a number between 1 and the odds number. If the two people say the same number, then the second person must perform the task.

A: Odds on eating a ghost chili?
B: 50
A: 3, 2, 1..
A+B: 37!
B: Dammit.
