What happens when you and a girl are doing anal sex and while her arse is up, you stick up so that you can use it as an axle and spin around it. Basically a vertical helicopter.
"Aw, Darla, as we were on our honeymoon and having our private time, he all of a sudden did a spin job! Can you believe it? I didn't know he was such a risky guy!"
