A beer that is drank in order to punish a friend who has been a douche, that previously belonged to that friend.
Chris was being a total douche so we drank his Bud Light as a punishment beer.
A beer that must be drunk warm and flat the following morning as punishment for thinking you'd be able to manage a whole can when you came home drunk, but in fact collapsed after just a mouthful.
Not to be confused with Hair of the Dog.
I kicked myself when I saw the almost full Special Brew next to my bed in the morning. Of all the punishment beers in the world, this was one of the worst.
