Riley 

She's sweet at times, but can be very stubborn. She's the friendliest person you'll ever meet. Unless she knows you very well, she will be very nice to you.

That girl is so sweet. Yeah she's a Riley.

Riley 

An extremely amazing guy who is extremely attractive. He has a huge dick and he fucks girls all the time. Sometimes he gets into a lasting relationship. When he is not having fun in bed, he can be seen with a couple close friends. He knows a lot of people but he isn't friends with most of them. He is very nice to most people and he can sometimes trust people a bit too much for his own good.

Bob: "That guy fucks girls all the time"
Jim: "Yeah, his name must be Riley or something"

Riley 

Riley is a gay whore. She is really hot and has great tits. She is kind of a "fuckboy" and will leave you on read occasionally. Don't hurt a Riley because she is a rare breed of emotional person. Riley will occasionally manipulate you but you love anyway. She gets very jealous but won't admit it, and when you get jealous she exploits it. Hold your heart close with a Riley because she will steal it.

I love 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.

Riley 

The child you purposely leave at the zoo because she’s not as good as the other sibling.

“Damn, I guess she’s the Riley of the family”
