From ContactJuggling.org

Done as it is named, as you reach for the stack with your receiving hand, you do a 4b propellor movement, while adding a twist of the wrists. The propellor part of the move can be done as many times as you like. You can also, aside from moving your hands back and forth, move them in diagonal directions also, this adds a climbing or falling effect to the trick.
