A science major of any kind. IMO the S needs more love in STEM.
Ever overhear them say "walkable" in a positive light.
Hobbies besides media consumption
Not "too cool" to learn something. Likes learning for fun.
Not to concerned with looking cool or badass, either. Look at CHUDs, I made a joke the other day that I can sense a decent bit of residual 90's 'tude in modern CHUDDery, and I think I'm onto something.
