If you do not know what the pee-pee slapping dance is, then let me enlighten you. The male of the relationship steps out either fully naked or, at a minimum, nude from the waist down. With a rapid oscillation of his pelvis, he sets his genitalia into motion, making a slap as his penis whips to the left, then right, then left again. He does this for several seconds, ending in a Ta-da, before padding away to wherever he was, fulfilled at a job well done. The impact is best if the audience, or shall we call her the victim, is in some innocuous space like the kitchen or laundry room.
