A flavored dip used on the nipples during sex which enhances sexual pleasure.
My favorite nipdip is chocolate.

When a girl dips her nipple into some sort of dipping sauce, and have a male (or female) lick it off.
"Hey, Charlotte lets go nip dip in some ketchup, and have steve and joe lick it off!"
