Pipe appointment

When a girl a guy dated briefly comes around to his place for casual sex.

Amy is coming around for a pipe appointment. I hope she doesn't catch feelings.

Drainage pipe

What an asshole is called when it starts spraying a fuck ton of liquid shit.

Oh shit, I can feel it coming! God wish my drainage pipe luck!

Exhaust Piping

This an act you do with your sexual partner with a vehicle, it's when your partner turns on a car, puts it in park and revs the engine as hard, whilst you insert your dick into the exhaust pipe and start fucking the car exhaust pipe while they are revving the engine causing your dick to burn

I heard Tyrone and baljiet did the exhaust piping!
