We all choose handle IDs for different personal reasons. What's the story behind yours? Ours, we were going to launch a computer store that was sort of super-heoricish, so we called ourselves The Tigerhearts, then we did some digging around, and turned out there was an underground society called Tigerhearts in England, so we had to add something to the name or change it. We liked the name already, so we added the word hackers to it. It was all we could think of.
Nemesis:
1. A source of harm or ruin: Uncritical trust is my nemesis.
2. Retributive justice in its execution or outcome: To follow the proposed course of action is to invite nemesis.
3. An opponent that cannot be beaten or overcome.
4. One that inflicts retribution or vengeance.

301 is actually 301A.D the year the first country in the world adopted Christianity=Armenia
Axisflame for me incorporates my two loves, 3d design (x axis, y axis, z axis) and fantasy, where otherwise rarely used words like Flame are very common. and plus it sounded nice, so i took it!
Mine is very simple Rene Adaimi 8-jan-93: the initials gives me Ra8
mine started out as memo (short for memory which my friends at school branded me), but my sister stole it, so as a retribution I stole her initials, turning it to mesa. The 177 thing was added later on when I started uni (it's my uni ID, with the year of enrollment ditched).

ironically, mesa also is a programming language and signifies the rising edge of a chip. Best of both worlds, software and hardware... Weird how that happened :)

I was Xelent [1993-2001] I used it as a nickname in old games and it was my first email also (i think xelent89@hotmail.com or xelent1989@hotmail.com) and then I used my cousin's nick Scorbido.
( I don't know what it exactly mean :P)
So i start using it in irc and then it evolute to scorz or sc0rz.

Haha Love that episode !
Very nice idea Tigerheart.Hackers, I loved this topic :D .
Well, why ILIA? My name is Ali, I dont know how I found ILIA as an ID? But wherever you find ILIA_93 it would be me, all my internet IDs have the same ID, pretty much all. Even my in-game username, PC account user name, all ended up named ILIA. :D.
Metalloy: well this a nickname I came up of it when I wanted to sign up for "www.ultimate-guitar.com" which is site full of forums and reviews... dedicated for guitarist. So I want it a name with a Metal influence to it ( dont get me wrong, I like metal a little but I am not a Metalhead) so Metalloy, why?:
it is a combination of Metal and Alloy, the intersiting part is that Alloy is a combination of Metals;) so Metalloy is combniation of 2 words which one of them is the combination of different types of the other;) I loved the concept and now anytime I sign up for something I used it.
Do I need to explain mine?

Googled your name, I got the the shivers rrrrrrrrrrrrrrrrr.

My name Shatilov.

I got it since my last name is Shatila

& the "lov" is how most Russian family names end.

So I mixed them

& got Shatilov.

I was fixated on Russian things at that time.
I'm a big Unreal Tournament fan, the UT99, not just the game play but everything related to it ! "Razorback" is the name of one of the music tracks in the game's soundtrack, it's not my favorite track but it sounded cool enough... Al thought my avatar features Mr. Albert Wesker himself (RE fan too) !
Badieh is my real name, but I usually go by the name of Grim Reaper, Grimmy, or Mr. Grim. Thus my avatar.

Why is that? I'm fascinated by such power to take people's lives, and the fear of death/afterlife.

It's nice to finally understand the meaning behind some of your usernames. I remember mesa telling us her story during our meeting last summer.

As for my username: samer, [sæːmər].
The lowercase version seemed more fluid and aesthetically pleasing.
as a boy's name is a variant of Tariq (Arabic), and the meaning of Tarek is "evening caller".
