Do you have a different perception or idea of a geek and a nerd? What do they look like in your head?

Would you say you're one?

Honestly, at times I use either to describe myself and I mean it in a positive way. But apparently some dictionary defines a nerd as unstylish and socially inept. Now, I think that's overkill. I'm neither and I know it.

But I say nerd in the sense that I am knowledgeable on some stuff and I like studying some stuff, and I say geek in the sense that I become very enthusiastic when certain topics are discussed.
