I was inspired by the ability of the small Kangaroo mouse to survive and thrive in the harsh climate of Dune. I asked the Fremen Stilgar, naib of seitch Tabr, what this creature was called and he replied “Muad’Dib”.
Well, the ones I wanted were gone. And I sorta stared at the screen, and just started typing stuff, and this was the only thing that looked even close to right. It wasn’t any of my other usernames online, but I’ve become much more fond of it as it gets older. And now I use it for other stuff, too.
I am originally from Arkansas. When I first moved to beautiful St. Louis, I was the brunt of a lot of “ignorant hillbilly inbred hick” jokes. So when I went off to college, I knew I would be talking to a lot of people from all over who might do the same when they found out where I was from. So I decided to make a joke of it with the screen name “Kissing Cousin.”
Well, the people online were a lot nicer than the folks in high school (isn’t that always the way?) and I got to be quite popular on the lists I was on. Soon my nickname was shortened to “KC.” I was also known as “KC Susan” sometimes. My brothers often call me “Suze” instead of Susan. KC Suze. There you have it.
As dorky as this is going to sound, my username was actually the character I played most on an online game (EverQuest). I use it for everything now pretty much.
Eh, Muad’Dib?
…from a Leonard Cohen song.
Sorry, I just thought that you were not done with your post.
Heh, no, that was it. I’ve heard the mean old lady bit a gazillion times, think it’s really feckin’ funny (especially considering the number of people who have told me this and my age), made it my user name. I wonder how many people picture me as this nasty old woman who’s grumpy all the time, as opposed to a nasty young woman who’s grumpy all the time. 
Square + cube = Sqube. I believe the drug was mescaline… nah, I’m just kiddin. I was like 12, and it came to me in a fit of inspiration that hasn’t shown hide nor hair of itself before or since. I use it for everything cuz… dammit, it’s the most original name I’ve ever come up with. Ever.
It’s pretty much what I came up with for my first e-mail address and every online thing I’ve registered for since. Pilot (what I did) and 141 (the airplane I was flying at the time - a USAF C-141).
I’ve moved through three airplanes (and out of the AF) since then, but the name has stuck - on aviation message boards people see pilot141 and know that its me. People here must think that there were 140 pilotXXXs in front of me, but there wasn’t! The 141 is an airplane! I chose the name on purpose!
I read a SF book where one of the characters refers to his significant other/lover/wife/slave (well she was kind of all of them, but it was a confusing situation - hard to describe in a quick sentence) as Waenara. It means “beloved” an an alien language. I liked the sound of it, and my typical usernames were already in use when I finally went to register - after lurking on and off for several years.
I used to use Zopz as an online handle often but afterwards it kinda lost its ring to me so I was searching for a new name to use. Jubbjubb? Yubyub? Honey Roasted Peanuts? or Gopher? I’ve been called Gopher by friends since middle school because according to one guy, I have a resemblance to a gopher he saw in a cartoon. I don’t have an urge to dig in people’s gardens but the name’s stuck with me through all of high school. So that’s my user name: Gopher
I don’t recognize your name. Did you change it recently?
When I first signed up I was working as an international go-between for some undersea fiber optic projects, hence the name sub- (underwater) -light (optics).
OK, got the name change - HiHorse has been retired to prevent further discomfort to my poor li’l old mammy.
Madame Zelda was the nickname given to me by my friends and coworkers who seemed to think I was some sort of psychic or mind-reader.
“Hey, Madame Zelda, what’s the investment value of stock #9355251?”
“$17,250. I’ll verify that for you as soon as you let me get out of the bathroom!”
No, really - that happened. Salesmen followed me into the ladies’ room to ask me this type of question - all the darned time!!
We even had signs made up for my office - “The Madame is In/Out”, “Minds read - half-wits half-price”, “Out of body experiences extra - out of brain experiences usual” - that sort of thing.
I can’t seem to sleep before 4am, and if I do, I cat nap. No matter how tired I am, as long as that clock says any time before 4, you can bet I am either wide awake, or thrashing about, trying to get at least 30 minutes every hour.
Strangely though, I feel rested, even though I hardly slept.
Ender, from Ender’s Game. Will, my name. I first started using it about five years ago for Starcraft online, had to use an underscore because Battle.net wouldn’t accept a hyphen, and I’ve stuck with it since.
And I’ll continue to pronounce it wrong, mwah. 
My user name? Simple. My name is Frank (or so my driver’s license says). I like to register with my real name whenever possible to avoid real life confusions. Unfortunately, Frank was already taken so that made me the 2nd Frank to register here. Ergo, I am Frank #2.
Yep. Story here, if you’re interested.
I should have called myself The Ultimate Newbie because in my ignorance when registering I thought username meant REAL name.(And just in case it was the name that would show up on my posts, I “customized” it by omitting capital letters and the space between first and last names.)Someday I’ll e-mail an Administrator to request a username change - if only so no one will mistake me for that Sacremento bishop.
