Three men is a triangle position. Each rubbing penis "stump" in each others face.
Seth invited Tom and Del to a Spring Hill Stump Grinder party. The all looked like glazed donunts in the morning.
The act of gay men rubbing their penises against each other, similar to scissoring for women.
Hopefully Denis shaves before he comes tonight, I’m not trying to start a fire when he hits me with the ole stump grinder.
