How is cheerleading performed

I need to know

Cheerleading is performed by (generally) several people, doing various flips, twists, dances, and other various movies, in addition to shouting certain lyrics in order to attempt to raise spirits at various sporting events and pep rallies. I say attempt because as of more recent years, people aren't quite as excited by them as they used to be. Furthermore, it used to be more about being spunky, but in later years it's been more about wearing shorter tighter outfits and doing more sexual grinding than peppy jumping. Don't be mistaken though, the original basis is still there.

Its performed by nubile young girls for the purpose of giving old men ad ugly people something to look at while football melon heads crash into one another and parents scream abuse at the opposite team
