Is when you put jelly and peanut butter in someone's asshole and you insert your penis into there asshole

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.

A sandwich comprised of Penis Butter (Sperm, Semen, Ejaculate, Cum, Baby Gravy, Baby Batter, Horny Muffins, Knob Slime, Peace Grease, Dick Goo, Ectoplasm of The Nether, Spoofs...etc.) and the popular personal lubricant K.Y. Jelly. Often said as a joke or sang in substitution of the old "Peanut Butter and Jelly " song features on the 90's popular kids TV show Barney the Dinosaur.

Other example: look up Barney Peanut butter and Jelly and change the words, you will see where the idea came from.

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?
