A drinking game involving a d-20 die and a standard 6-sided die. Playing in a group of 4 or 5, one person challenges another player to a duel. They both role both of the dice. Whoever gets the higher role on the 6-sided die is the winner. The loser must then drink for the number of seconds the winner rolled on the d-20 die. If anyone hits 17, this is the "Grizzly Combo," and everyone must kill their beer automatically. A dorky game, but great none the less.
