YoYoJam DarkMagic
Plastic Whip
 
Start with a Sleeper. (You are going to want a fairly unresponsive yo-yo for this trick)
 
Make an L shape with your throwhand. Bring your thumb down in front of the string and then turn the hand up towards your body so the string is hanging off your thumb.
  Bring your hand up and swing it forward creating a loop over your thumb. The string should swing forward down over the yo-yo. End with thumb in front and your middle finger pointing behind.
  Although there are many dismounts out of this, I simply dropped off the string. Return the yo-yo to your hand.
