riley 

a girl who is very mean and arrogant and calls everyone bitches behind their back. mostly everyone doesn't like her except for her very close friends who are very dependent on her. her clique is very exclusive and she pretty much talks about everyone behind their back. she thinks all the guy have a huge crush on her and all the girls are jealous. girls want to be on her good side even if that means selling out their best friends. overall, she is not a nice person (although she thinks she is).

ugh that girl is so mean, she is such a riley

Riley- 1. Referring to a person that does not provide for themselves, lives off of others supplies, and offers no compensation for what they take. Also see, mooch, sponge, leech, vampire friend, cookie stealer

2. Referring to a person that cannot tell the truth about anything, lies about simple things, such as, where they are, who they are with, and lying. They have a tendency to blame others and make their freinds scapegoats

3. Referring to a person who has a "so called" straight life style (possibly even a baby) that displays overt homosexual tendencies, also tends to like Madonna

a riley will lie about lying, then have you lie about lying for them. They also will burn holes in your carpet, bum cigarretes, and never drive anywhere.
