Riley Knox is often rich. But not from his own money; from his daddy's. He often SAYS he's love with your cousin, and she with him. But he will also cheat with a slut named miranda.

(a girl from ARKANSAS)
and then accumulate genital herpes :)
Cousin: I miss Riley...
You: Girl, hes got some nasty itches in places they don't need to be!
Cousin: oh yeah i forgot, hes dating miranda.

a dumb bitch who thinks she can get any guy she wants. but really no one likes her, it's quite sad, you will laugh at her when she is sad. a riley also looks like big bird with a big ugly nose. you might wanna stay away from a riley. she'll just end up using you, and leaving you for new better people.
that girl was acting like such a bitch. yea i know, she was a total 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.
