A muff-bluff is a situation in which a man or woman falsely assumes or is even tricked into believing that a woman would like to engage in sexual intercourse. The term is derived from the slang word muff or muffin (vagina) and the gambling term "bluffing." While a "muff-bluff" is the noun form, there is there is also the verb form "muffin' bluffin'."
