Bio: A forwards, off axis spin where your hips do not go above your head
Cork: A backwards, off axis spin where your hips do not go above your head
Rodeo: A backwards spin where you flip completely (hips go over head)
Misty: A forwards spin where you flip completely (hips go over head)
Flatspin: A variation on a backflip, where your hips and shoulders become even in the air. It's very similar to a rodeo, it just looks slightly different, and if you are to do more than a flat 3, you will spin once the flip is complete.
Hope that helps
