Stands for peanut butter, jelly and jizz sandwich. Before performing any sort of sexual act (i.e. fucking in any hole, rj's, bj's, tj's, ej's, or jj's) lay out two pieces of bread next to each other, one with peanut butter and the other with jelly. Right before ejaculation pull your skeet cannon out and shoot your knucle children all over the bread with the jelly. Put the bread with peanut butter on top of the piece with jelly and jizz. Enjoy them on the spot or cut the sandwich into four, put them on some nice china, cover them with saran wrap and bring them to a cocktail party.
Mary: "Wow! I love what you've done with these PBJ squared's! They are so zesty! Were you fucking up the butt?
Thomas: "No, the bitch was Mexican."
