Popular in climbing circles, the Reverse Captain Hook requires extreme finger strength and dexterity. This maneuver entails a girl standing up, while you do pull-ups between her legs, supporting your entire body weight with only two fingers in her vagina. If done correctly, should result in an orgasm.

Andrew: "Bro, that's fucked up!"
