Honestly, according to this diagram I'm more of a geek than a nerd. Personally, I would define those two terms backwards. A nerd is defined mostly by their intelligence, whereas a geek shows signs of all three. Then again, I don't like the sound of geekheroine as much.
I do have my fair share of social ineptitude, but that's usually conscious and I am able to contain it if I so choose. That does not, however, stop me from blurting out things like "You know I don't like you right?"
