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!"
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!"

The most heinous sexual act. So terrible that your friends can never speak to the girl you gave it to ever again. In addition, they are not allowed to be friends with you for a month. At the end of that month you'll still think it was worth it.
Where's Jim been?
I don't know, I can't be friends with him until August since he gave Jane a triple decker peanut butter and jelly sandwich.
Oh my god! That's awful.

The less controversial version of "they go together like peanut butter and pickles". it means that 2 things go perfect together.
Jon: dude, Cheese and vodka, like, they go together like peanut butter and jelly.
Davey: Wtf? do you mean they go together like peanut butter and pickles?
Jon: No, what made you think that?
