Like an attention whore but even worse. This type of female not only craves attention, but feels entitled to it. She feels so ridiculously entitled to attention that she will bad mouth anybody who does not give it to her. What makes this kind of girl even worse is the fact that when she does bad mouth the person who isn't giving her the attention, she will often do so to many people, spreading dirty gossip and/or lies, in hopes of damaging that persons reputation. She can become very front and/or back stabbing, all because she didn't get the attention that she felt she was entitled to.
Justin: Hey Pedro, Monica is totally talking shit about you, and telling every body how your such an ass hole!
Pedro: Yeah, she's just mad because I ignore her when she tries to talk to me.
Justin: Why do you ignore her?
Pedro: She is completely fake, and I don't associate with fake people.
Justin: She talks all that mad shit on you simply because you don't give her any attention? Wow, what an attention predator!
