I like girls that are a little bit uncool. To the rest of the world, they seem suave, sophisticated, they've got their shit together. But, behind closed doors, I want a woman who is not afraid to let her inner geek show. I tend to have my best relationships with these women.
And, since I know you're going to ask this question...no, I am not dorky at all. I'm as cool as the other side of the pillow at all times.
