The act of masturbating and then ejaculating on another's back.
That crazy bum just gave my little sister a Wooly Willy!

Like a tea bag, to stick your saggin balls on someones face while they are sleeping, but shave you balls while doing it, and arrange the pubes into the shape of a Moustache or Beard
Look, I Wooly Willy'd Ian, and now he has a beard.
