Similar to female on female scissoring, a Scissor Piston is the sexual act of two MALES scissoring. During the sexual act, each male interlocks taints and has his penis inserted into the other’s rectum while making a pumping piston action.
I walked in on a couple dudes doing a little Scissor Piston in the bathroom at the rave Friday night. They were squeezing each other’s nut sacks like turkey basters as they pumped away!

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!

1 of the best or arguably the best basketball team in the NBA right now. They play great defense and have a balaced offense which lead them to a 64-18 record this season. best in the NBA!! also made the finals for the last 2 seasons, winning the NBA title back in 2004 against the LA Lakers. Easily have the best starting 5 in the NBA with Chauncey Billups, Richard "Rip" Hamilton, Tayshaun Prince, Rasheed Wallace, and Ben Wallace.
