peanut butter and jelly: sock 'em in the belly!
A kindergarten game where one kid says the refrain, "Peanut Butter and Jelly!" and another kid repeats it. After the second kid says it, the first kid says, "Well, sock 'em in the belly!" and lets fly a fist into the second kids stomach.
Kid #1: "Hey! Say this: "Peanut Butter and jelly!"
Kid #2: "Okay. Peanut Butter and JellY!"
Kid #1: "Well, then, "peanut butter and jelly: sock 'em in the belly!"
(Followed by a sucker punch to the solar plexus.)
Kid #2: "Ouch! you friggin douche!"
