Haha, I cut the sound on the Side, I think. I totally forgot about the Double Flash and Gainer half. XD I only realized that after I had sent them though. -_- Stupid me.
Sideflip(Class A)- A trick in which the performer jumps and rotates 360° about the z-axis over their shoulders before returning to their feet. While being known as the most difficult of the three basic flips (Back, Front, Side) to learn, it actually proves to be the easiest to execute.
Gainer-Half(Class B)- A trick where a person performs a gainer and spins 180° at the same time before landing.
Double FlashKick(Class C)- A Double Flashkick is a back flipping technique with 2 complete Flashkicks executed in the air prior to landing.
I dunno something like that? Probably have people that are more knowledgeable with the last two add a bit to them.
