A generally happy person but can be VERY moody. If you're not their friend.. chances are they dont like you. They know what they want and will do whatever it takes to get it .. normally they do.
They tend to be very pretty (blonde usually) and sometimes a little ditzy because of the attention they already get.
most guys like them.
sometimes they can be whores and back-stabbers. but they can be pretty funny and entergetic.. some are very atheltic which can cause the competition between others.
"wow what a whore.. but she can be nice sometimes"
"must be a kayla"
"damn my man is flirting with her!"
"probably a kayla"
"shes crazy.. "
"that would be a kayla"
