The Piston 

n. A sexual maneuver between a man and a woman/pwn victim/Pruger in which the man retracts his testicles up into his lower stomach and then shoots out one testicle at a time, alternating testicles with each blast. This is an alternative form of The Shotgun.

The NBA team The Detroit Pistons got its name because the founder of the franchise could use The Piston with extreme speed and accuracy.

The Dutch Piston 

Not to be confused with the heterosexual Dutch Rudder The Dutch Piston is delivered in two methods beginning with the Four Stroke Method: It begins with two men placing the ends of their penises together while gripping losely on their foreskins. The two uncontrollably begin rolling their foreskins over the adjacent penis in an alternating fashion. Thus creating a pleasurable piston like motion.

The Two stroke Method: “This method is similar to the Four Stroke Method.” It is accomplished when one man rolls his foreskin over the other mans penis while in a stationary position. The inconsiderate stationary man most likely has both hands on his lower back, knees slightly bent and has a large enthusiastic grin on his selfish face.
The two methods are calculated in RPMs not unlike a piston in an engine. RPMs in this case are defined as, “Rolls Per Minute. Although the Two Stroke method is unscientifically rated for higher RPMs, the Four Stroke Method is and always will be beneficial for both parties.

First Used in a sentence: Year 2017. Origins unknown but, most likely common at Antifa gatherings and historically between Spartan man couples as a last chance of ecstasy before dying in war. They were into all kinds of weird shit.

What began as a surprise party at a local hotel dining room was swiftly interrupted when two men where caught engaging in The Dutch Piston behind the coat check counter. Both men with intense focus and enthusiasm did not disengage until the Police arrived. Surprise!

The rusty piston 

The result of having rough anal sex, and your shaft is covered in feces and blood, giving it that rusty color.

I ran into my ex last night, and the rusty piston was on my bucket list.

In Halo it is the incredibly overpowered yet ONLY weapon to use if you wish to survive. Three head shots will take the shield off and kill the person being raped.

The pistorius

Grabbing a stranger off the street forcefully leading them to an alley and forcefully putting your amputed leg up their anus but yelling surprise before hand so it isn't classified rape and leaving them to bleed out from their anal wounds.

Did you see that person left in the alley,they must have received the Pistorius
