A crazy ass, supercilious fool, who will stab you with a rusty knife if she sees you holding Ricky Young's hand. REGARDLESS of the fact that they've been broken up for 6 months and she gave someone else head moments before.
SOME BITCH- "Courtney, that was really lame that you screamed at that girl for holding Ricky's hand... You guys have been broken up for 6 months, and you just have Kevin head... Plus, you made a huge scene, and embarrassed all your friends..."

COURTNEY LATTA- "LYKE, OMG, I CAN'T HELP IT?!!! I'M LYKE, JUST SUCH A PSYCHO, OMFGGG!"

SOME OTHER BITCH- "Yeahhh you fuckin are hahahaha"
