A term used for stuck up females. They never answer your calls, they ignore your text messages and they have you added on Facebook but don't acknowledge or say nothing to you when they see you out in the public eye unless you say HEY first. Attention whores who give no "PLAY" to only boost up their own low self-esteem by allowing the guy to endlessly chase them with no hopes of ever building a REAL friendship/relationship. The type of chick that will give out her number when you ask for it just for the hell of it to mislead the guy and to boost her own morale. These females are usually damaged-goods. They've been hurt in the past, and they usually have a lot of male friends.
Rambo: (Texting some girl who hasn't been replying back to his text message lately) "Man Cornelius, these hoes be acting stiff."

Cornelius: "They be acting stiff Rambo?" (Not an actual question, but almost like agreeing). "I told you these hoes ain't worth your time man, delete her number, leave them alone, they're nothing but attention whores who just want to mentally build themselves up."
