PBR is Pabst Blue Ribbon. It's a type of beer that tastes like unholy ass, but has become popular amongst the Hipster crowd. It used to be dirt cheap, but since Hipsters buy that shit by the truckload, it's gone up in price significantly. Hobos have since gone back to drinking each other's urine.
I have yet to get something that's actually mixed.
So far I've gotten Southern Comfort, served on the rocks; vodka, served neat; red wine, twice...
My music is trying to make me an alcoholic.
