Twilight

Every generation has their vampire stories.  My generation was Tom Cruise in "Interview with a Vampire", originally a novel by Anne Rice.

Now there is a bunch of those crazy teenagers all over the cast members of Twilight.  I think this Oatmeal article does a pretty good job of describing these fans.   By the way, this applies to women of all ages out there that still think they're 13.

How Twilight Works.
