3 lefts make a right. If you take the long way around instead of the direct route during a spinning trick you are doing a Holger.
A Flip to a Leg Vault
The dog uses the player´s body as a launching pad to jump for a disc. A Vault is a leaping catch from the handler’s body. The dog leaves the ground for the target... is a cool trick, but it becomes cooler if you turn 270 degrees in the wrong, or unnatural direction, instead of the natural 90 degree turn.
The Holger is a great piece of Athletic Humor
Athletic Humor is like telling a joke with your body. Jokes are funny because they walk you down a familiar path and then dump you out somewhere totally unexpected. You can do this... that takes simple sequences and makes them flashy and special.
In this image, the handler made three 90 degree right turns instead of a single turn to the left to make this vault happen.
