What is the meaning of your username / nickname?

"sciaenops" is the first half of the latin name of my favorite fish, the red drum. aka, sciaenops ocellatus. its an artifact from when i was taking marine biology. "22" has been my lucky number since i was in first grade.

Guitako is a mix between guitar and otaku... My girlfriend came up with this Name because i love my guitar and animes\mangas :D

It's a nickname from middle school based on my nickname Trey.

Roggan is the thing the villagers in Age of Empires are saying sometimes and was my very first PC game.
And 29 is the shortcut for this chat phrase in Age of Empires 2 which is my favourite RTS till now.

Simple, Oh shit!

Because fallout

I thought I already seen topic like this here, but whatever, I'll tell again.
Some time ago I decided to change nickname to something that easier to find (when you say "search for my nickname on steam" and there is like a twenty users with the same name - it's no good), so when I was sitting and thinking about it I look at my cat, and thought "Рыжий хвост" (sounds similar to "ryzhiy khvost", the nearest translation is "ginger tail" or "red tail"), and then I thought - hey, that would be nice nickname! So, I make it one word with connecting vowel "e", transliterate it, and took it as nickname. If you pronounce it in English it's probably sounds different than I intended, but I don't want to change it now :)

Motor Head Lyrics from Deaf Forever ... Horses scream Viking Dream drowned hero's in a lake of blood ...and i've been using it for so long i forgot when I started using it.

"Mosasauridae" is a family of extinct marine reptiles known as the mosasaurs. :) Really cool creatures; they were apex predators in the Late Cretaceous oceans and some even attacked other mosasaurs, haha!
So cool.

MaKiPL

Ma - First two letters of my name.
MaKi - Name in japanese. I'm into japanese things, so yeah.
MaKi+PL - This is of course country code, which I could replace with something else. I don't know yet with what.

EDIT: Almost forgot. In Polish movie "Haker", there was a main character- Marcin Makowski, whose friend called him "Maki". I probably stole it from there. My nickname is... 10 years old?

It's a ball of cheese. I've been using it since the mid 90's

I honestly have no idea. Ive been using since i was 8.

it's a mix of the vorpal sword from alice in wonderland and my name, carolina! :D

I used to like this...band when I was younger.
Nickname could basically mean "someone who likes that band". Silly. But ehh... I never had luck with having proper nicknames. I just suck at making them for myself so I stick with that one, basically because I don't see a point in creating another one when I would start to dislike it over time just as with any other before. Though in sometimes I reversed it to get Kiniap... that went a bit better, but I didn't change it to that

igel, or correctly, Igel is the german word for hedgehog. I'm a bit on the short site, nearsighted and sport a spikey hair cut... so Igel.
I use the lowercade i because I gets sometimes misread as lowercase L. And 2005, because that's when I first used it as a internet nickname, in RL I've been called the first time decades ago.

First letters of the three words in my normal username. I actually don't like it that much here, but I don't want to change it ;_;

The username I normally use originates from third grade or something O.o

i was initially going with WolfTree
A tree that manages to survive through a damaged state
wolf trees dominate their surroundings, taking nutrients and sunlight enabling competition to grow
I didnt like the name so i went with UlverCarvalho
Ulver means Wolves and was my favorite band at the time, carvalho is my last name, and also a tree

Republic of Mancunia (or Republik) is a thing associated with my favourite football team and that was my username on a football forum I was on. Found that Uranium Falcon Bicep was a anagram of Republic of Mancunia not long before signing up here and I thought it sounded sort of funny/quirky. It was in my mind when picking a username here only I changed the Bicep to "Punch" for the hell of it because a falcon punch is a thing related to gaming.

bzhknight : bzh is for "breizh" the name of my region in its own language, and knight, simply because i love playing as the knight protecting the vow and the orphan blablabla, not much to say about that^^

I live in Singapore which has a very humid temperature thus i used muggy convert it to mug and knight is to prove my existence as an warrior living in such a hot climate Country :S

Mine is complicated

I can't sleep in Japanese (眠れない)
