I'm with you SimuLord. I have no clue at all about comics and I despise anime. I also don't like Star Trek but I absolutely love Star Wars. I guess you could call me a geek based on games and some of the movies I watch, though. I don't dress geeky. I wear name brands and stuff. I go out with friends.
But I can tell you the meanings of words like DOT, AoE, apm, fps, hud, reticule, ~, and more. I'm a pretty hardcore gamer and that's geeky. Very geeky. Oh, and did I mention I'm in Computing Sciences? That's also kind of geeky.
I'd say I'm geeky but not a geek. You're part geek but it doesn't define you.
Sidenote:
I really don't like the geek-chic movement, though. "It's cool to look like a geek as long as you aren't one". Brought on by that disgusting show, Big Bang Theory, it's now cool to spout random quotes of things you don't identify with and wear shirts saying "E = MC LOL IM A DORK SO IM COOL".
This sort of thing:
Girl: OH I SAW A NINTENDER ONCE AND I OWN A WII THEREFOR I WILL WER DIS BAG HER N SHOW MA LOV CVUZ ITS RETRO LOLL
Guy: i haff plunger lolll im totalli not a hispter doooshbag
Other guy: Sup ballas, I gots me a pink fannypack. It goes so good with this shirt of that green dinosaur thing. I think it's called a Birdo?
