From YoYo Wiki
Also known as boing-e-boing.
The Boingy Boing is a cool looking trick but is also very hard to learn, so if you can't get this trick try, try, and try again.
[edit] Instructions
To start this trick you need to perform a split bottom mount, after you land it flip the yo-yo forwards like you were doing a barrel roll but stop once the yo-yo starts moving forwards.
As it starts moving forward let your yo-yoing hand slide down so the yo-yo will move forward, then quickly bring it back up (this will cause the yo-yo to move towards you). After it reaches the other string let your yo-yoing hand down again.
