Long Island Dip
v. The gentleman, who may or may not be from Long Island, whilst nude, lowers his balls into a prepared chalice of mouthwash (i.e. Listerine) of any chosen variety (i.e. Cool Mint) and then places said balls into the open mouth of a willing participant who then gargles, relishing in the refreshing sensation.
Linda's mouth was feeling not-so-fresh after eating at that Italian restaurant, so Jim lovingly gave her a Long Island Dip in the back of his car.
