You/your Geek can remember all of the hiding places in the most complicated level maps in any PC or console game ever made, but can't find the car in a parking lot when it's the only green one there.

You/your Geek laugh at computer store commercials because "People pay tons of money for that crap, and it's so easy to do yourself!"

Harddrive smells like Ozone and starts making a clanking noise? No problem, you're/your geek is on the way to Tiger Direct/New Egg for parts. Car, clothes dryer, or air conditioning unit smells like Ozone and starts making a clanking noise? "Dad" is speed dial #3.

Asking if he/you want to go out for his/your birthday gets the reply "No thanks. Let's play WoW/TF2/Wii/Xbox and order pizza."

You/your geek decides to use a power tool and says "Don't worry, I've played 135 hours of Resident Evil IV. I know how to work one of these things."

You/your geek hesitates to adopt a kitten because it's going to chase the game controller cords/mouse.

LOL Geek right here :: at Robbie The Programmer Guy::

I'll post more as I find/think of them (because I have a feeling this place is crawling with Geeks of one stripe or another) but everyone else is welcome to chime in.

Has figured out -- and memorized -- the algorithm for THAC0 and, incidentally, knows on which page of the second-edition manual that table is located. (Addendum: People who have to ask "second edition of what?" aren't yet at this level of geekdom.)

Considers pwning Rock Band on Expert a legitimate affirmative to the question, "Do you play an instrument?"

Is thrilled when his/her preschooler rocks the PC version of Blues Clues.

When someone else mentions good fishing in a certain lake, this person replies, "Which server?"

You know he's a Geek when;
Your friend sees a pretty girl across the room and comments; "Damn, I'd like to integrate her function! "..
This same guy also thinks "What's yer OS, baby?" is a good pickup line......

You know she's a Geek when;
The aforementioned girl upon hearing the "What's yer OS, baby?" Line thinks to herself; "I'll bet he doesn't have the processing power of an Apple IIe.."

And of course another hint she might be a Geek is if she replies; (with a sneer that would make Snape proud) "Linux, you idiot! What else??"

Otis, my husband swears he decided to marry me because I was the only chick who could spend seven hours playing a computer game and then go to a gaming con and win a prize for roleplaying vampires.

In short: geeks mate. I think it's in the genes.

You both might be geeks if conversations like this take place in your house (while playing WoW, no less):

Him: "You know elvish. What are they saying?"

Her: "Not that well. And that's not REAL elvish anyway."

You know you're a geek when July 15th was like a long awaited holiday...because Harry Potter was finally released.

Went full-on elf at the ROTK premiere. I remember something being said about "Arwen's evil twin."

*sigh* I really wish I had my own geek. As it is I have to hide most of my geekiness (unsucessfully) from any potential boyfriends and then ever so slowly, in very tiny stages, reveal the truth.

I usually give the game away when I say something like: "Antony? You do realise that means flowery don't you? From the greek 'anthos'. What's your middle name? James? Oh you must have been born in the early 80s. That's when the name spiked in popularity."

Shame you're across the pond. I know a bloke that would think that's cool who is in dire need of a female of the geek persuasion for epic rounds of... sitting in his library reading, and the occasional snog-fest.
