You know when you slap a bowl of jell-o and it jiggles. Yeha that's jell-o slapping. But what do you think when you see it jiggle? It could be meat beating, or booty spanking. Or opening doors, taking out the trash, playing Nintendo, any thing your mind desires.
Jell-o slapping is so relieving but my mom says it's only okay if I do it while I'm at school.
