Wow this is actually a long story lol.
Our Advance Science Students group was commonly refered to as the Nerd Herd. No clue why, but everone started grabbing Greek letters and the word nerd or geek or whatever. One dude was Alpha Nerd, there was an Omega Dork, Beta Nerd, even a Lambda Nerd and I somehow got Gamma Geek. Actually, I got Geek Ray first, but I refused to let anyone call me that. Really it was the stupidiest thing in the universe, but my name was the only one that stuck. At least at has a nice alliteration to it.
I got geek instead of nerd (there's a difference, but thats not relevant) because I play WoW, used to play DnD, I'm antisocial, I'm obbsessed with weird crap and geek sounds better than nerd with Gamma.
As for Gamma, I got that special because one kid smartly commented it would take a few cm of lead to keep me away, I was high energy no matter how calm I acted, and I was a serious health hazard in large amounts. And people wondered why I was so antisocial...
