if you actually want to know, here's what i think each is.
Cork: spinning with your head and feet on an even plane and spinning like a barrel roll. feet are leading
Bio: same as a cork, but head is leading.
Flatspin: just imagine flipping a turtle on its back and spinning it. easiest way to think of it
Misty: A frontflip with a spin, but off axis. if it is completely straight (like and aerialist) it is a front full
Rodeo: backflip with a spin which is off axis like a misty
D-Spin: an inverted cork
i think thats about it. i dont know why an underflip is, so i cant help there. and remember: TRICK NAMES DON'T MATTER, JUST DO IT!
