reverse 360 piston jammer

The advanced art of standing in front of someone, inserting your fingers into their anus, then forcefully rotating your wrist 360 degrees, it doesn't matter if it breaks, slowly insert more of your arm into the anus, then another forceful 360 movement, this time on your arm. Once this is completed, a full bottle of gorilla glue is applied to the arm and anus, locking it in place.

John: Hey Peter, why is your arm mangled?

Peter: Because I hit Dave with that reverse 360 piston jammer!

John: Peter, you're dead to me you retarded nigga.

Pittsburgh Piston

A term used to describe when someone is getting their dick sucked or rode by a person while they’re driving a vehicle.

“Hey, do you mind if I give you a blowjob while driving?” she said. “Oh, you mean a Pittsburgh Piston?” I responded.

“Dude, get this. She rode my dick WHILE I was driving! Ain’t that crazy?”
“Damn! That Pittsburgh Piston must’ve felt nice…”
