When you walk in the streets looking for sniper's spots, or when you move an invisible mouse to move the camera (eg ur head, to look around :x...)

Worst , was when I played Eve online, playing all weekends, setting your alarm clock for important operations or just switching skills. That was nerdish.

... when your at work all day creating web pages and you can't wait to get home.... to create a web page. :/

When you get jealous of a kid playing their D.S. where you work because you want that to be you.

When you play Call of duty moderwarefare 2 for a FUCK LOAD and you see a wall and behind it you think theres a camper waiting to kill you or...when you see a little tree garden and think wow this would be great for a team death match...

sometime, when I walk outside, I have the song Onett from earthbound in my head.

Yes. Like me: Hyrule Field!!

well, i know i'm a geek cos everyone calls me one.

but when you spend 40 minutes trying to explain to your mum (who doesnt care really) that the guy isn't called Zelda, that's Link.

and the same woman then tells you every time you get too hyped about a game "it isn't REAL. Can't you go and get a REAL life and talk to some REAL people?"

burn.

and, of course, the good ol' game dream. i once dreamt i was Toon Link and i had to fight Adult Dark Link. i mean come on! Toon Link, seriously? what's HE gonna do? i spent most of that dream running away.

when someone hands you something and you hold it above your head while loudly humming "dundundunDUNNNNNNNNNN"

You know your a geek when you try to glitch in in real life to snipe some n00bs, happens to the best of us...

When you get ALL of Futurama's jokes.
