At work, we've sort of given each other unofficial nicknames around the office.  Mine, for instance, is Liubird: a play on my last name and a bluebird, since my business attire usually veers toward the color blue.  Now, we just got a new employee this week.  Her name is Cindy Deanna Rom, and hers comes off as a natural acronym: C.D. ROM, a nick she's admitted to wearing on her lapel with pride since, well...... CD-ROMs came about.  This is right up there with one of our supervisors, A.T.M, aka Akshat Theodore Mehra. :)

Outside of work and online, it's Angie, of course.  My little niece calls me Auntie Ang, usually by my request.  And my older brother used to call me Dirty Chicken, for um..... undisclosed reasons.  (And like several other names from him, that was certainly NOT by my request.)

Anyway!  Do any of you have nicknames, either given to yourself or by others?

I've been called the following throughout the years, by a variety of people:

Doubleton (word play on my last name, by my boss)
Moose (because I was the biggest guy, age 18)
Singleberry (another word play, not sure of the origin, just one weird person used it)
The Stomach (based on my appetite, by people at work)
Cowpoke (age 12, by some strange guy in my art class)
Arnold (by the gym employees at my old gym; I was much more muscular in my early twenties, about 20 pounds heavier)
Solitude (by some guy in 4th grade)

One guy thought I was a chemist because I was talking about science. He was very strange and lived in a tent by a lake.
A girl once called me the antichrist because I ignored her for an entire shift at work. Everyone agreed that that was pretty extreme, which made it kind of funny.

We have nicknames for each other at work; bad thing is most of them are pretty insulting:

Everyone calls me "Baby Huey" which is actually an insult if you know of the cartoon character but I honestly get into enough arguements so I didn't bother to fight it. Most of the time they just call me Huey. One guy actually calls me by my last name which is the way it was in high school.

The Professor/Golden Boy:
This guy doesn't work with us anymore and I'm extremely thankful for it. He spent everyday telling us how much he was above working our kind of work and how he was going to get into this hard to get in school. Everyone called him "The Professor" because he looked like one - a smarmy one in my opinion - and was always on his cell phone like he was important. I called him "Golden Boy" because he had his future planned out and everything was going to go his way -  a little thing called life may have something to say about that.

25 cent/2 cent/Powerpuff
Ugh... this guy is annoying and he should have been fired last Friday since he maxed out his points in the absent tee system. Anyway, he's viewed as a burnout so my supervisor started to call him "25 cent" because he was only worth half of what 50 cent was but then as time went on he decided he wasn't even worth that as a worker so he started to call him "2 cent." Later, when he got switched to another shift he got some tattoos of stars near his right eye for "his dead homies" so then he became "Powerpuff."

Ceasar
The co-worker I have the most problems with says he is of Roman decent and likes to be called "Ceasar." No one does though...

Manchild
This guy no longer works with us either but the name is rather creative in two ways. The first is he dropped out of high school to do cyber school because he thought going to normal school was too time consuming because he wanted to work so he could have funds to race is stock cars. Basically, he was in a hurry to grow up. The other reason this fits is he's 18 so he's techincally a man but he acted like am inmature teenager (or child) so he's a man that acts like a child.

Scuba Steve
To be honest, I really have no clue why we call Steve "Scuba Steve." Yet no one just calls him Steve.

I have a few nicknames, but they're pretty close to my actual name:

T.C. - for obvious reasons.

Top Cat - play on my initials.

Travis - When I went through my No More Heroes obsession, I grew out sideburns that looked like Travis Touchdown's, bought aviator sunglasses and spiked my hair up very high. My gamer friends started calling me Travis, and every once in a while it still comes out in conversation. I also use this as a karaoke name when I'm somewhere outside of the usual circuit.

T-Bizzle - someone I used to work with called me this. He used to shout "T BIZZLE!" from down the hall. I kind of miss it, and I still have no idea where the B or Bizzle came from, nor did I ever care to ask.

T-Pain - Meaningless nickname that I'm growing quite fond of.

Tommy Rock - this was a nickname given to me by a friend who likes metal, and now it is my karaoke stage name as well as the one name that people usually refer to me as. I am perfectly OK with this.

Tommy Tulip, Tommy Gun, Tommy Tantra, Tommy Knuckles - plenty of other nicks that have no relevance. Except for the Tantra one, but I don't think I'm going to type that whole story out.

I am a very nickname-y guy, apparently. People have trouble just calling me Tommy, which is fine.

EDIT: I forgot one: T-Money. When I was at uni I had good luck with certain things, so my dormmates used to say that "Tommy C. is money", and that got shortened to T-Money.

When I was workin' the restaurant biz, we had this old (by which I mean ancient) Italian woman working in the kitchen. She couldn't pronounce my name properly (Brandon), and the way she said it the first time sounded more like "brandih". She was making a brandy based sauce at the time, so everyone just called me Brandy-Sauce.

My close friends decided it sounded a bit too childish, so they just call me Brandy now. I like that one.

I hate it when people call me "B-Man". My little sister does this all the time.

Waaaaay back at 7-Eleven, I used to get teased (to say the least) by a lot of folks for looking Jewish (the dark, wavy hair, I guess), so one of my co-workers used to call me Nabron because it sounded Jewish to him. Later he started calling me "Nabron the Defender" for whatever reason.

Talking online, people just call me by my handle, or "Idolo" for short.

Is it correct to imagine you lookin' like a female Phoenix Wright? 'Cause that's the image I have right now.

Big Daddy reference, I would think.

One of my friends used to call me "The Miker" in high school.  In fact, we had others in that group such as "The Chrisser" and "The Fortiner" (his first name is Tim and last name is Fortin but we couldn't use his first name cause we already had a "The Timmer" haha).  Not sure how that got started but that's why I call myself the_miker online.  As some of you may remember, I used to post here at STC as "Mike" back in the day.

-Mike

Carmen   My proper name is Ranjit but I don't really even use it outside of official documents or whatever.  My mum calls me Sasha though, and guys in my high school used to call me Jeter (after the Yankees player) for... God knows why

..Shoe.

or Shoebonics/ Tom Flax.

My coworkers aren't big on nicknames, but I've had a few in the past:

Burger Time: Up through 4th grade. Inspired by the similarity between my surname (Berg) and the now-forgotten video game.
Data: 5th-7th grade. I was good at math.
Hindy: Short for Hindenburg. My karate teacher was the only one who ever used this one, but he used it a lot.
Johannes: A reference to a joke I once made about having composed the Yohannbock Concerti. If you don't get it, say my full name out loud.

I don't think I had one in high school or college.

That one took me a while--I originally read it with the Mandarin pronunciation. But you're Cantonese, aren't you? Is the Cantonese Liu pronounced more like it rhymes with blue?

So that's why someone thought I was you one time. I once knew a middle-aged woman from Taiwan who could never get it right. It wasn't just that she left off a trailing consonant or something--she never got more than the first syllable right, if that. Bread, Brad, Bren, Brian...She must have gotten it wrong at least 50 times, even though I showed her my ID several times. Do people also call you Brendan a lot? Brandon is a much more common name than Brendan, but three people out of four (I'm talking about native English speakers now) will say "Brendan?" when I tell them my name. Maybe I'm just not saying it clearly enough.

These days, I'm mostly just Josh. ... although when I was in college, the women loved to call me Joshy. Some even got away with it!

My mom's best friend's family (yikes!) calls me J.B., my initials and I used them in my first year or so at STC. I don't actually remember what drama sparked me to change to my current handle.

My best friend's wife calls me Joshua. Somehow, she actually manages to make it work...

Word, son. Happens all the time to me.

That's an affirmative on both fronts.  In truth, I always thought the Mandarin pronunciation was the same way.  *shrugs*

Now I'm recalling one obnoxious classmate back in the seventh grade, who always used to greet me with a "Liu-who!" every time I saw her.  You know, like "Yoo-hoo!"  Clever the first two or three times, but she went on doing it for the whole damned year.

I always thought "Liu" in Mandarin was very close to the pronunciation of "green" in Mandarin.

I haven't been called many non-insulting nicknames over my life, but there are two that stand out.

"Tanger" - A few guys in my past just appended "er" to my last name.

"Pootie Tang" - An old male colleague at a previous job used that on me.  He specifically used that in reference to the movie of the same name, which I heard was a somewhat funny movie.

Alright, I've acquired a new nickname that has to be my favorite.

So a few nights ago at work, I was jokingly hitting on one of the waitresses (and not doing a terribly good job of it) when one of the managers spots me and gives me this goofy look, to which I say "Smooth like Antonio Banderas".

He responded with "More like 'Branderas". He's been calling me that ever since.

I've actually got some decent nicknames in the past...

Rolling Thunder

My junior of high school, there was this posse of girls, I kind of talked to each of them. At one point, they coined the nickname "Rolling Thunder" for me. They eventually just shortened it to "Thunder." Made me feel like an action hero! I don't know why they called me that, but I never was the kind who backed down from a fight back then; I think they admired the fact that I always stood up for myself. Either that, or they called me that either jokingly or even mockingly. A possibility I've never discounted. Maybe they just thought I was loud? Either that, or they thought I looked like the hero out of that old video-game, Rolling Thunder. I'll never know...

Rolling Thunder

Leon

First year of college, someone coined this name for me. Don't remember why or how, but it stuck. Still kind of use it today, seeing as how I still talk to some of the people I first met back then.

Auron

Second year of college, awesome nerdy chick I dated for about 3 months, I let her borrow my copy of Final Fantasy X. She started calling me Auron; I wore a trench coat in the Autumn months, and an overcoat in the Winter. I also had a pretty conservative pair of shades...not too much unlike Auron's, but not intentionally so, either. Still, good shades. My voice and mannerisms probably made her draw a comparison, too. Also, beard.

(She was nice, but when I was talking about something, she often misunderstood, and thought I was talking about something completely different. That, and she often wanted to talk about things completely different from what I was. After awhile, I just didn't think we were on the same wave length, and mutually, we eventually just stopped talking with each other...)
