kuzuki mushu
(KUH zoo KEE moo SHOO) The sex move when a woman does a handstand against a wall while a man simultaneously swings on a pull up bar (or anything that would serve a similar purpose) and inserts his penis in her vagina/asshole as he swings in. Acknowledged as one of the most difficult and dangerous sex moves known to man.
Dude I got a pull up bar yesterday and my girlfriend is a kinky bitch so I'm gonna kuzuki mushu with her. Hopefully I don't crush my right nut.
