Zipper Dinner

While zipper dinner is typically used to describe any type of fellatio, some suggest that it may satisfy certain criteria to be called a zipper dinner.

Some believe the fellatio must be performed to orgasm. Others suggest a zipper dinner should be used exclusively for homosexual fellatio where the person being fellated keeps his pants on, usually because the act occurs spontaneously in a moment of passion.

There is also an assumption that the person fellating does so enthusiastically, as if they are devouring a good meal.
