Unless you've been living in a shoebox for the past 12 years (yes, Mean Girls is TWELVE YEARS OLD - let that sink in for a moment), you're probably well acquainted with a young woman called Regina George.
Two-faced, manipulative and always putting herself in front of everyone else, she's the definition of the Worst Friend Ever, or even Worst Enemy Ever.
Only, at times, you catch yourself smirking along with her. At times, you even want her to win.
Is that kind of bad? Maybe? Definitely? Oh well.
