They think they're hotter than everyone else (but they like talking about how they just like wearing jeans and t-shirts) they like sports (but not as much as they like telling guys how much they like sports) and they just don't get why they don't have any female friends (although what they really love is saying that girls are bitches and they don't want to be friends with them anyway). They're not just girls who are friends with guys, they're girls who proclaim that they can't stand other girls, only want to have guy friends and simply will not shut the fuck up about it.
They are the worst girls.
The worst girls shine in their Facebook pages; where they post statuses about how glad they are that all their friends are guys because girls are awful, and tons of boozy photo albums called things like "my boys <3." Don't get me wrong, it's great that you have boys. I believe that guys and girls can be platonic friends, sometimes. But sorry, if you're a girl who hangs out solely with guys, probably about 50% of them harbor feelings for you or at least a vague sense that they might want to make out with you sometime when everyone's drunk, 45% of them want to sleep with your roommate/sister/mom, and maybe 5% of them want to actually be your friend.
A lot of actresses also suck in this regard. (Megan Fox, I'm looking at you). They're champs at saying things like "Women are just so jealous, I really just prefer guy friends" and "I'm really just a guy's girl, I love football!" (I'm sure you do, January Jones). These factoids--especially the sports (because imagine! A woman who likes to watch sports!)--are constantly trotted out in profiles of actresses like they somehow make them more interesting. So, ladies of Hollywood (because I know you're reading this) it's quite possible that the reason you don't have girlfriends isn't because they're all jealous of your hotness--it might be because you're just really annoying.
Now, I shave my legs and everything but what the hell ever happened to sisterhood? This is simply not cool. If you do this, you are not fooling anyone. We all know that "girls are so jealous" means "I think I'm hot shit, you should too," and that "I just get along better with guys" means "I think all girls except me are bitches." We all get it. But if girls don't like you, you need to a.) take a look at the girls you're hanging out with and b.) take a long, hard look at yourself. Because somebody's acting like an asshole and it might be you.
So ladies, here's the takeaway: stop trashing other girls as a way to inflate your ego, because it sucks. It does not make you remotely interesting or unique that you like football. It just makes you one of millions of other people who like football. (And dudes: I know a girl who can hold her liquor and talk intelligently about sports is hot--not that I can speak from experience--but think twice about dating a chick with no girlfriends. Just...think twice). Most people couldn't care less if you want to have friends of the opposite sex and watch sports and drink whiskey and do whatever other crap "guys girls" supposedly do, so you can stop talking about it now. Sorry, but those are just things that people do sometimes. You're going to need a new schtick, cupcake.
