What is a geek?

Non-geeks keep telling me what a geek is. Geek is such a broad term that most anyone can be a geek. I consider a person to be a geek if they are willing to be called a geek.

What is a geek chick (or whatever she chooses to be called)? Someone that accepts the title geek, and is female, or considers themselves to be of the feminine persuasion.

Yes this is the short version, but the full version of what is a geek/female geek, is easily 10-20 pages. While the long version will be explain here, slowly, this seems to be as simple as I can get.
