The act of getting a naked person (either one you really hate or really love), lube up a slip-n-slide, positioning your "partner" doggy style at the end of the slip-n-slide. Once this step is complete lube up the nose of a baby shark and proceed to slide the baby shark nose first down the slip-n-slide into your "partners" anus.
