Get the Piston Cupmug. Take someone who is face down ass up and lube up your arm and repeatedly punch them in the asshole until your whole fist and arm enter. After it is in, then proceed to pump your clenched fist in and out. Making your arm bend and extend having the look of how a piston works. Hence… The Stinky Piston.

Get the Stinky Pistonmug. 
Where a woman gives a man oral and the man uses two dildo's on the womans vagina and anus. With all three actions simotaniously it resembles the workings of a motor. Continue until desired affect.

Get the PISTON SHUFFLEmug. When you use a piece of toilet paper you had just blown your nose in to wipe your ass, hoping the mucus would act as an adhesive and pick up any particles left behind. May also be used when low on toilet paper, but desperate. Named after the Minecraft object.
Barry was unfortunate enough to have both the cold and the flu at the same time, and when low on toilet paper, resorted to the Sticky Piston to kill two birds with one stone.

Get the Sticky Pistonmug. The mating call of a rare bird that inhabits the car engine. Identified by a loud screeching sound upon ignition (not to be confused by a worn out engine belt)
"Did you know that your car is making a loud screeching noise?"
"Yes, I think it's a red-tail piston bopper.
It's a mating call."
"Yes, I think it's a red-tail piston bopper.
It's a mating call."
