Approach the wake just as you would for your normal tantrum. Come in with a good strong edge, and get ready to back off and stand tall off the top of the wake.

As you stand tall off the top of the wake, turn your body a little more then you do on a tantrum, so that your back starts to head towards the boat a little bit (notice the position of the rider in the picture). This helps you have a bit of rope slack.

Keep your arm bent and the handle in tight, and initiate the rotation by throwing your arm, shoulder, and head away from the boat.

Keep your arm and elbow up longer then you think you should, if you bring your arm down early, you'll only rotate 180 degrees. As your legs catch up to your upper body, start to spot your landing.

Bring your arm down to the middle of your body to stop your rotation to land. The landing is similar to a tantrum landing, so getting the rotation down is the hard part of this trick.
