Honestly, I don't see what your supposed to do with a cheerleader who can't back flip? Kicking her off the team is where I'd start, then again, we'd never have this video to laugh at.
We all know someone who tries to wow us with their backflipping capabilities...usually when they're trying to show off for the opposite sex, friends, or just drunk. Have you ever seen someone do this, and secretly wished they would tank it so you could laugh at them...
