When giving a person a hand job and anally fisting them and they ejaculate in your hand. You then pull your hand out of their ass. Now with one hand covered in semen and the other covered in fecal matter, you slap them together to mix the mess on both hands. Finally, with your hands still together, you thrust them up the persons ass as fast and deep as you can.
Person 1: Dude this guy gave me a PB and J last night.

Person 2: That is disgusting...

When two people go really, really well together, like peanut butter and jam. They are almost always in love and are like each other's foil: a person who complements another person and highlights the best parts of each other's personality. Thick as thieves. Partners in crime. Hand in hand. Copesetic.
