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…”

Rail Pistols

A handheld electromagnetic weapon that uses two parallel rails to accelerate a conductive projectile (often a small metal flechette) to hypersonic velocities. Rail pistols are the sidearm equivalent of railguns: compact, powerful, and with minimal recoil (the projectile's momentum is offset by magnetic forces). They offer greater velocity and armor penetration than conventional pistols, but they require enormous capacitor banks and produce a distinctive electrical crack and muzzle flash. In speculative military use, rail pistols are favored by officers and special forces who need to defeat body armor. Real‑world prototypes exist but are bulky; a truly compact rail pistol remains a goal of advanced weapons research.

Rail Pistols Example: "The bodyguard drew his rail pistol—a chunky, snub‑nosed device with a capacitor pack on the grip. One shot later, the attacker's body armor had a neat hole and the attacker had no chest."

Energy Pistols

A handheld directed‑energy weapon that fires bolts, beams, or pulses of charged particles, plasma, or coherent light. Unlike slug‑throwers, energy pistols have no recoil, minimal sound, and can be dialed from “stun” to “vaporize.” They are the sidearm of choice for space cops, cyberpunk runners, and anyone who doesn’t want to explain bullet holes to the landlord. Drawbacks: battery life is measured in shots, and overheating turns your grip into a branding iron. The ultimate equalizer – until your power cell dies mid‑duel.

Energy Pistols Example: “He pulled his energy pistol, set it to ‘warm’, and the mugger’s gun melted into a puddle. Then the pistol beeped twice and went dead. Classic.”

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.

Grandpa's Service Pistol

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...

Guy2: But... that's a shotgun.

Guy1: Yeah, "Grandpa's Servoce Pistol" is just what I call any weaon left to me by a dead family member.
