I can't trust anything Cady says anymore. Her nasty behavior, her conniving attitude, her double-dealing actions, she's really turned into a mean girl.
Noun- one who let's an obsession over a high schoolboyfriend dictate the way they treat those around him. This creature is notoriously deceptive and conspires with a fellow mean girl to torture her ex's new love.
A little whore who tries to fit in by being a bitch. Most are abused by their family and turn to drugs and sex when they are older. Usually, the mean girls are seen in Middle school, High school, and sometimes college and late elementary.
