An in depth sex maneuver when a man shits(coco-) on his balls(-nut), then cums on them(cream-), and finally shoves his balls into a vagina(-pie). The coconut cream balls can also be used to tea-bag an unsuspecting victim for comedic effect.
Jennifer: What did you say he did with his balls?
Betsy: He gave me a Coconut Creampie for desert. It was fantastic.
