Taking a shot of beer every time the leader of any NASCAR sanctioned race completes a lap. The winner is determined by whoever lasts the longest during the race. You are allowed to 'crash' by taking a shot of 80+ proof liquor, and giving one other 'driver' the same shot. This is allowed once per driver. You can have as many drivers as possible, and they can form teams to 'crash' other drivers.
Hey are you coming over for the NASCAR Race during the Daytona 500? It'll be a good time.
