Acronym for Budweiser Miller Coors. Usually used in a disparaging way to refer to beers that have no flavor and thus must be served ultra-cold to disguise their putrid taste. Also can be used to refer to the people that drink aforementioned crap beers, who think the only purpose behind drinking beer is to get drunk as quickly and cheaply as possible.
I brewed a good summer ale for my barbeque, but since I knew the BMC crowd would be there too, I bought a case of Buttwiper just for them.
