What is Bifmuf?
BRA I FYLLA, MEN UT TIL FROKOST
Norwegian, means "Looks good when you are drunk, but have her out before breakfast"
Often used after a "one night stand" when you realise that you had sex with something that looks like a Hipopotamus :P
Hun som ble med meg hjem i natt, var skikkelig BIFMUF ass...
