1.
A game played by hippies, drunk people or a combination of the two, Dave Matthews fans.

Required Items: Folding chair, plastic cups, beer, 5-10 coins, panties (clean or dirty)

Numerous drunks stand in a line and signal the "pantyballer" by screaming "PANTY BALL!!!!" in unison. Following the signal, the pantyballer throws their rubber ball at a folding chair lined with panties found strewn about an outdoor setting. Pennies are then launched in the air from the force of the rubber ball and players try to catch a coin in their respective cups filled with 1/3 of a beer. Whoever catches the coin or the most coins becomes the pantyballer.
