A hard sexual position to pull off, it requires three people, one holding on to something suspending all 3 people in midair, while the other 2 do a 69 while holding onto the hangers ankles. While doing the 69 one of the hanging partners reaches up and fingers or jerks off the person supporting everyone else.
Man 1, "Hey, I heard you tried the monkey's hanger last night with Jim and Jill."
Man 2, "Yea man! It was awesome, my arms are really sore though."
