This list actually goes along the categories of naming a character The last one is pretty funny though.
I feel that such name as "Noobgotstabbed" would make me somewhat overly-aggressive in the game, comparing with "Stabron" which sounds kind of noble and not pulling into brainless gankfest (corpse camping included).
I generally go for a name which sounds plausible within the universe even if it doesn't actually have a meaning or a use elsewhere. For example, I had a warrior called Reysal as a kind of twist on the more common name Ray or Raymond. I like things to be immersive as much as possible personally, I don't get naming yourself something outlandish it just diminishes it for me.
Also I know I'm reading way too much into this but when rogues have names like "Stabby" something as res previously mentioned it reminds me of the people who are like "Lol u fukn gey with ur rp sht get rekt lel kek"
I always try and keep names as short as possible, although I'm not totally certain why. I suppose it's partially because I believe that with a shorter name it's easier to remember. For example, if I was selling something in the trade channel that I'd soon have more of, a player may not want to add me as a friend but in an hour or two they'd remember about me and very easily 'w/ Slud' due to it being such a short name.
Another benefit of having a short name is that it looks and sounds great. Having one or two syllables in a name really makes it seem more genuine, and perhaps even more intimidating, if done correctly.
These may be my own thoughts, and perhaps others disagree, but I've always used short names - even though this can prove very difficult at times as shorter names are usually taken.
Long ago I just came up with it for my Death Knight alt in WotLK. I suspect - though it was not intentional - that the name was subconsciously inspired by the all-popular Nyhm at that time, but I wouldn't say it's a complete ripoff and there's plenty of other people with this name as well. Since them, whenever I did decide to make alts, I just went with derivative names (Nymesis. Nymexis. Nymerial. Nymix. etc.).
To me. it's a cryptic word, born out of "nemesis" and "nimble". I stuck with it because it stuck with me over the years.
I use Toastea because ever since I played Mortal Kombat I have always said "Toasty!" When doing something awesome. An amazing head shot in a shooter or a crit in D & D etc. Toasty is usually taken by someone less deserving, so I usually go with Toastea. I also like Toast and tea coincidently
For a long time I've gone with variations of my username
Hogbobson <- Main
Hoglockson <- Warlock alt
Hogbankson <- Bank alt
But I do also like proper fantasy names, and I might go back to that model for classic, for immersion's sake. My first warrior's name was Regg, and that stuck with me for a long time. I was also ecstatic when I met the druid who bore the name Reg - we definitely did not fight to the death. :D
A couple year's ago on a TBC server I had a tauren Warrior named Cortept. Anagram for protect. I was quite proud of that one - it's a plausible sounding name that also satisfies my closet linguist. <3
90% of the time I choose a lore-ish name that suits both my class and race; over time I have opted for making them easy to pronounce and remember for the sake of TS communication etc.
For the upcoming retail Vanilla servers I am probably going to go with something slightly out-of-place, such as "papapriest" or "wildshot" (for a hunter), or "tinyblast" (for gnome mage). bc why not ;P
