Why are all the mean and popular girls the same?
Blonde, their faces filled with makeup (what writers like to call "caked with makeup"), dumb, bitchy...
I mean, cmon, if you're gonna have a mean girl, have a little variety.
Not all mean girls are blonde. And not all mean girls are drowning in their own makeup.
Not all mean girls have to be sluts (which basically means they have affairs or sleep with many different people) or so dumb they can't tell their right from left.
But in stories, most of them are. I guess it's just a huge cliche and stereotype for blondes to be dumb and mean, in stories and real life. And it's getting ridiculous.
Seriously, y'all have been watching too much Mean Girls.
