When a female/male kneels behind a male while he is standing and has an erection. The kneeling person reaches between his legs and grabs his erection like a microphone, pulling it down, then sticking their thumb up his ass with the same hand. Then they squeeze their hand tight, not unlike that of a gas pump handle.

to masterbate. pumping the pipe originates from the ancient art of placing a hand over ones shaft and moving the hand in a linear motion making sure to pull back the foreskin exposing the urethra ready for ejaculating the semen.
A popular misconception of this phrase is doing the same hand motion whilst urinating to give the false impression of a constant stream of clear semen but infact its just piss.
