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…”

Take someone who is face down ass up and lube up your arm and repeatedly punch them in the asshole until your whole fist and arm enter.
