I used to be Rubang B on my old profile, 'cuz that's my nickname in real life and pretty much my username for anything for the last 10 years. Then one day my profile died and I couldn't log in, so I came back as a ghost.

back on the Disturbed (the band) message boards my name was One Disturbed Canuck, I shortened it to O-D-C to be accepatable on any kind of forum

now it dosent really mean One Disturbed Canuck anymore its just O-D-C

It was some random nickname I came up with when I first started playing online multiplayer for Socom II(I'm Indonesian, and I'm a dude). I stuck to it since for most of my interweb usernames

I always read your name like somebody's trying to say "oddyssey" and pronouncing it wrong.

Maynard, the lead singer from Tool, which is my favorite band

When I first started playing age of empires I really sucked. And my buddy said I was a damnd l0ser at it to give it up. So the name stuck with me even though I turned out to be quite good at AOE and most other games I play.

Nothing like getting your ass kicked by a damndl0ser. :D

*****EDIT*****

Live decided that Damnd was a little too much for them, apparently its a naughty word.  So they took the name away from me thats why my live account is bornl0ser.  

My name and the first 2 letters are the initials for the city in China where i was living (HuangShi, 黄石） at the time of making my profile.

my nickname in school because I had the highest grades in school, won a lot of academic awards, and then got a scholarship to a very expensive and prestigious high school.

professor also rhymes with my last name, and my nick name irl was theprof or profness or professor nesser. The double 0s comes from the year in which I came up with the idea of using it as a screen name. It was the year in which I built my first computer from parts. Before then, I'd never owned my own computer.

I use it for nearly everything.

my PSN name, Aortictwister, came from a randomized set of dictionary words. It was the first adjective and noun that came up.

Diablerie is an online gaming name that I have used (unless taken) since way back in the day.  Thankfully, I was lucky enough to have it available here.
