Amusing and useful sport created by Steve Purcell in his Sam and Max:Freelance Police comic books. Essentially, it's abusing canned beerlike substances (the "beer" made by large-scale U.S. and Canadian manufacturers - you know: the stuff that tastes as if it's already been drunk once - think budweiser{see American Beer}) with large clublike objects until the cans explode. It's quite fun, if a tad messy.
