Butwiper; Another name for Budweiser beer, because of the massive amounts of morning shits created by drinking excessive amounts of the beer.
Dan: Fuck that man!! Never again!! I shit out two loafs of bread and three bowls of rice this morning because of that butwiper shit I drank all night. Next time its Miller time. Tom: I hear that man!!
