brain 

Any individual (male or female) who posesses an I.Q. greater than 170 who is completely absorbed by books, music, and other subjects not remotely related to sports. The opposite of a jock.

Co-worker: Hey, did you see the Eagles games last night?

Me: That's none of my concern; I'm not a jock, I'm a brain.
