Regina George(Rachel McAdams, left) in "Mean Girls"
Catchphrase: "I know, right?"
Weapon of choice: Consignment to social hell
Why she's here: High school queen bees may be prettier than male bullies but their gift for psychological sadism renders them more dangerous. As tartly created by Tina Fey, Regina is one of the meanest and therefore one of the best. (All votes for Nancy Allen in "Carrie" will be counted.)
Bully rating: Three fists
