Cosby Sweater
In light of recent abuse/rape charges, the Cosby Sweater is a sex act during which the man eats a Jell-O pudding cup yelling, "Zippity Zoppity, here comes my floppity!" as he ejaculates. For the family planners out there, the act can be taken up a notch by ejaculating into the empty pudding cup.
You never walk down the pudding aisle the same way again after getting a Cosby sweater.
