slackjaw

A game in which two people try to keep their mouths slack for as long as possible. The person who smiles or closes their mouth first loses. Like a staring contest, only with a slack jaw. Best if done in really boring classes, across the room from each other.

Jane and I had the best game of slackjaw today! It went on for fifteen minutes, but then the teacher called on me and I had to stop.
