A gay threesome. PB&J meaning Penis, Butt, and Jizz.

Also an overrated sandwich that is easily outclassed by lunchmeat.
John put the P in Tim's B, and Dave started to J all over them, completing the PB&J sandwich.

Peanut butter & jelly (or jam in the UK) is the best fuckin' sandwich ever (behind meatball sub). I found it via Reggie & The Full Effect.

The act of smearing jelly on the ass of one partner and peanut butter on the ass of the other. Both get down on their hands and knees facing away from each other and proceed to slam their butt cheeks into one another until the jelly and peanut butter are clearly spread and mixed. Whenever the partners see fit they may stop, take a piece of bread, wipe their partner's butt cheeks clean, and consume their prize.
Honey, break out the tarp, we're gonna get our PB&J on tonight.
