A method used for cleaning your
rear end. To perform the "magic hand", lather soap onto your hands
real good, usually turn your hand sideways, and use your lathered hand to scrub inside the crack. Though there's no telling how long this method has been used, it was comedian/actor Jay Mohr who coined
the term, "magic hand".
I had worked 12 hours, and sweat my ass off. The only way to feel I've successfully cleaned my
sweaty ass was to give myself
the magic hand.
She was kind of a freak, dude. When we were
in the shower, she let me give her the magic hand.
