1. A seemingly sweet, pretty girl who pretends to be your friend, but turns out to be a bitchy, boyfirend-stealer.

2. A poser.
1. I'd like to punch Gabby in the face.

2. Don't be such a Gabby!

A low down, hoe, skanky, trashy, ass bitch. Can’t fight for shit but want to run her mouth. She think she the shit but she not.
Gabby is a dumb ass hoe.

A huge bitch that cheats on all her boyfriends and is the fakest bitch on earth. She will manipulate you and hurt you and make you hate yourself. Get away from her and don’t fall for her trap. Gabbys are huge assholes and you should stay away from all of them if you don’t wanna get cheated on. Gabbys are very flat and look like ghosts.
Person 1: Holy shit that gabby is such a whore!
Person 2: I know right!

She is the most unpleasant person to be around. If there is a Gabby at your school the change schools because it that bad. She cries for no reason, is a snitch, and wears so much mascara at the age of 10. Or to most people -2.
