No not all of them I know some really nice smart ones
Definitely air-head, non-thinking, people whose sole purpose in life is to be perky, bubbly, fun, and mean.
There is a tendency for them to be kind of air headed or flighty but most of them are not as bad as movies and tv make them seem. I mean hell I think I am worse than most I have met and I am not a cheerleader.
Worked for a university that would host cheerleader camps all summer long, thousands of cheerleaders would come for those camps,they got on my nerves. Some of them are flaky, some OK, mostly loud when they start cheering inside the building (ear-popping loud).
not really - it's a stereotype
