Playtex Piston

When two men or women get on all fours with their anuses pressed together and push a lubed tampon back and forth between their rectums.

Don't throw that used tampon away, me and Bob want to do the Playtex Piston.

Pisser pistol

The process of shooting out bullets of cum with a brief time period between, similar to how a semi-automatic pistol shoots. This is whilst you are sitting on the toilet pissing.

She was surprised when I pulled my new move, the pisser pistol in the costco bathroom.

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…”

The Screaming Pistons

A sexual act involving your cock, if you’re a dude, or a strap on, if you’re a chick, and a vibrator. You stick the vibrator up your girl's ass and fuck her doggystyle. As your dick (or strap on) goes in-and-out of her snatch, you use your stomach to move the vibrator out-and-into her anus at the same time. The variable motion of your cock (or strap on) and the vibrator going in-and-out of both holes resembles a couple of pistons. Hot to watch, fun to perform and, if done right, you’ll both end up screaming.

Jane cummed five times when Dick gave her The Screaming Pistons.

Those two lesbians are doing The Screaming Pistons.

The Screaming Pistons is like double penetration without the third person.

Any weapon left to you in a will by a relative. Not necessarily a pistol, or even a service weapon, but usually. Generally left with an instruction not to use it for anything retarded. Usually in very good condition.

So named because of the stereotype of a grandfatherleaving his favorite grandson his service pistol.

abbr: GSP

Guy1: Hey, where are you going.

Guy2: Taking Grandpa's Service Pistol to the range...
