look up any word, like jamflex:
The handjob equivalent to "Wood Chipper". When a woman finds that squeezing, twisting and yanking on a penis isn't satisfying. Thus calling her a Pipe Wrench.
Man: "Dude, I heard that chick gave you a handjob"
Dude: "Handjob!? She was a pipe wrench!"

This occurs when either yourself or your girlfriend is jacking you off and pulls a BIT too hard.
Damn! She gave me a pipewrench last night and it still hurts!
