An ongoing game in which one player bets any other player to do something they would not normally think of doing for $1. Bets are often things such as; tackle a newspaper stand, eat 7 Texas sized jelly beans all at once, drop kick a parking sign, say something random to a stranger, or do just about any other ridiculous thing that comes to mind.
Most often, even if the person carries out the bet the dollar is not exchanged. The purpose of the game is for people to do random shit that they don't normally think of doing for everyone else's amusement.
dollar bet: I'll give you a dollar if you can drink the entire pitcher of beer in under 60 seconds.
