Equates to a turn-around jumpshot in basketball. May be accompanied by a shimmy shake, a little razzle dazzle, or ooh-ooh shoulder.
Jordan just hit that turn-around J to win the game.

Can be used in a connotative manner: Oh man, I just drove right past our destination, I better pull a turn-around J.
