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...
