Everybody knows Twilight is lame.
But guy who plays Edward is, like, totally cool because he hates Twlight.
So it's okay to fangirl guy who plays Edward. And stand in line for hours at the mall with a cattle band on your arm to get his autograph, because you hate Twilight, too. You're cool. Not like those other fans.
And, by extension, it's okay to get all het up over Twilight. In order to hate it. Because that's cool.
You should probably buy a t-shirt while you're there, so you can wear it ironically.
And go see the movie, because you'll be sooooooo annoying to the regular fangirls, with your coolness and your irony.
