I want to point out one other thing just on this thread, which is a small sample set.  My name is “Animal” and Bera’s is “Bera.” We both made a catchy, easy-to-remember name, with a clear theme, obvious associations and an embodied point to make.
You are sensor first, followed by feeling – yet your user name is a collection of letters that can’t even be pronounced, and I have to look back each time I type in order to remember it.    Puffs and Rondo are both spelled out names, but the meanings are more elusive and don’t evoke a ‘body.’ Puffs comes closest, in that I can actually picture something physical – like puffs of smoke. But that’s smoke. Something that your hand goes right through, and that doesn’t stay and leave a visceral impression.   The most embodied name among Alphas here is Auburn, which is a color; but not an animal or a visceral being or concept. Other Gamma names on the forum are very “is what it is” and viscerally evocative also. Thanatesque, Arya, etc.

An interesting thought, @animal!
What about Fae/Faerie? Though I have to say it wasn't a spontaneously chosen name. It was suggested I pick an easier name with an easier nickname and everyone was saying I was giving them twins vibes with 'Tea time', so I thought of a similarly abstract name but one that was also about something I was personally fond of and came up with Faerie Tale. Then on the second day I realized that just the first one would do/was complete, and dropped 'Tale'. Then Jelle nicknamed me Fae and that stuck so much, it became almost like a second real name I have. If someone shouts "Fae" somewhere IRL, I swear I'll turn around without remembering (at least for a few seconds) that they used my CT name.
Also, Puffs name didn't make think of smoke. It made me think of a short, plump, Black man. The exact opposite of what he actually is, lol. And I always thought Kaze was a freckled ginger of medium height, like a real life version of Archie Andrews. I don't remember where my ginger association with Kaze came from but with Puff it was his name. He used to have the word 'Cheese' in front of it, I think it was 'Cheeseumpuffs' or something like that. And that kinda mixed up in my head as "A shorter, plumper Diddy/PuffDaddy," somehow.

puffs' name is indeed a shortening of Cheeseumpuffs, which was my first ever email I made when i was in sixth grade and since no one ever uses the username, it's a guaranteed first try name when I'm making new accounts on pretty much every site ever.
it's not meant to mean  or evoke anything, and i'm perturbed by how much ego people seem to have placed around the identity since it is -- while not meant to imply it by the name -- essentially smoke, as animal said.
 
At the moment my current username I'm using more often (usually for online chess these days) is slabadoof.

oh no, i'm all ego these days -- that's not what i'm trying to say -- following the smoke is showing signs of fire to come, for sure.
i just don't see puffs as an identity that fully represents me anymore, to the extent that it -- and the many other names, nicknames, games and "identity evasions" i create -- is a sort of smoky haze that circles around and between myself and others and when i see people latch on to the names it gives the distinct impression that that's where they've decided to stop in terms of their understanding of who you are.
 
I gots an ego forsure. I just call it "me" though

@Bera
To me, @umbilical-sphere has meant something connected to the source, smooth, perfectly shaped, connected to life, to something beyond... it seems to fit him nicely, no? His personal path and spiritual goals seem to be embodied in this simple visual image... And possibly hints at his Ne not needing a concrete thing to relay that meaning
I love his name <3

@auburn
Yes, in the case of Ne, it seems like what says something about them is the process in which they choose names, rather than one specific name itself.  I would argue that their choices still reveal something about them, even if their process did not involve thinking "what does this say about me?"  Because they literally could pick any word in the universe, so the ones they choose reveal something, at least about how their minds work, even if not something that defines their central identity.  Also, the pattern of words over time reveals something about their 'style' or personal touch.
But in Delta Fi-heavies, the name choices tend to evolve around a few concepts that say something about them in a very direct obvious way.  Alphas (on the whole) seem more willing to throw out the idea of identity for the whim and the wordplay; whereas Deltas (on the whole) seem to incorporate the wordplay into some sort of personal Fi ideal or message.
 

case in point

i actually had a dnd character for a bit that was a half-orc barbarian i named Asmod after asmodeus.

Copying this from my about-me post because relevant

Aliases I have gone by online (‘cause I feel like oversharing):
MagicDreamer
my very first online alias, back when there was nothing much to do on the internet except have an alias ;p
Song_of_the_Ocean
my second online alias, created back when everything oceanic was my obsession. It’s the alias under which I first contacted my husband and it is still my Yahoo alias today
flightysprite
my original twitter handle and website domain name – I still own the domain flightysprite.com, but there’s nothing there anymore
shelleyintherain
my current wordpress-blog alias and what my youngest sister used to believe my name really was XD
MountainShelley
my current Twitter and Tumblr alias. I still love the ocean, but my home is in the mountains <3

@auburn
I had a PM discussion with a friend last night who identifies as TiNe (though she hasnt been confirmed).  I just wanted to share how I framed it:

the TiNe who wrote CT, calls it like.. alpha ghost tendency
like obscuring the visceral desires
but he is very emotional too
[re: TiNe]
yea because the opposite and inverse is SeFi whose desires and feels are most embodied, visceral and immediate
but
no type makes someone more emotional per se; its just how it's directed
so my theory is TiNe can be really deeply deeply emotional
but its less at the surface

Not excellent wording on my part, but it was a PM discussion 😛
The main point I was telling her, which I strongly believe, is that any type can have just as many emotions as another type. But the way they frame or embody it may be different. There's a different rhythm to its expression. I don't think Alpha Ghosting tendency is per se, incorrect; but more that they express their emotions more ephemerally and may resist being pinned down to one identity; or fully embodying the emotions in a visceral public way.  But their emotions can still run incredibly deep. I think your explanation above is excellent and it shows how this feels from your own perspective 🙂
From my perspective, i do not perceive you guys being less emotional than anyone else. On the contrary, Alpha NTs often strike me as having a lot of emotions swimming beneath.
 

Excellent analysis here--I like where this discussion is going!

But Ne’s allocentric perception and Ti’s beside-itself reasoning (third-person) makes it so they can feel like they’re simulating their own experience, real as it may be. I’ve heard Alpha NT’s describe it as them controlling their body like a puppet. They also play with identities like toys. Try on many hats. Try on many ideas. We might say each one is human and alive — but there’s still a fleeting quality to any specific rendition.

You know, just the other day, I was thinking about how Ne parodies are quite literally a kind of embodiment. But they're are only a fleeting embodiment of a particular moment in time, and one whose specific content doesn't particularly reflect the Ne's identity. (I suppose what does reflect their identity is their propensity to do parodying in the first place).

It is soooo difficult for me to come up with names for anything. I typically just use some variation of my real name in every single forum or something that symbolically represents my real name in a slightly more abstracted way.
With this forum I had to take more care since I wanted to be more anonymous, but it was incredibly difficult to come up with something. I thought about it for a long time, and I was still only able to think of a name that may be traced back to my actual name if one were smart and got the reference and made the connection if they knew me. Basically it’s almost impossible for me to think of something that will completely divorce my alias from my birth name.

@bera hugs that is adorable! ?
my coworker describes me as someone who is “constantly coming up with wild ideas” and in art school they praised me for my innovative ideas and my work being like nothing they have seen in their decades of teaching art, so I know I am creative with ideas. I’m just not great with names. I associate naming things with Ti especially. NeTi and TiNe seem to be the most creative namers IMO.
