The act of rubbing butter on the clitoris of the woman you are trying to seduce. You then continue to munch on the buttered clitoris until the woman experiences an orgasm.

Once you whip out the butter, there is no turning back.

This does not apply to "I can't believe it's not butter" or margarine.
