Usernames, wow. I haven't actually gone through too many. The first I'd ever had had something to do with owls, and I made it when I was six, haha. I don't really remember it too well, maybe it was "nightowl," but honestly I have no idea. Perhaps I just liked owls at the time, I don't really remember why I chose that username.
The first username I clearly remember using on multiple websites was "katemaxo12". I made it when I was maybe eight/nine, and was mad when I tried making an email with it because my usual password for it was too short. "kate" was a nickname for my name, the "maxo" part literally came out of nowhere, and "12" had been my locker number year after year, so it became my favourite number.
A little while later, I came up with a new username, the one I signed up for FH with-- "narwalpanda54321". At the time, the Narwhal Song had been one of my favourites, maybe it had recently come out, I don't really remember. Anyways, I couldn't spell "narwhal" correctly for the life of me, and consistently left out the H. Of course, who doesn't love pandas? So that also go thrown in. The countdown from five is, yet again, a concept that came out of nowhere. Don't question the fourth-grader logic, dude! Some spin-off usernames I've used have been "narwalpanda", when "narwalpanda54321" is too long; "NarwhalQueen" because idk; and sometimes just simply "Narwhal".
Another username I've signed up with is "Maggie727". Maggie is simply the name of my cat. The "727" didn't entirely come out of nowhere, as my friend had put it at the end of multiple usernames, and I kindly borrowed the idea. Another username I've used in the past is "lilliana1289." The "lilliana" element came from me really wishing I had that name, and "1289" came from my favourite two numbers, twelve and eighty-nine. Perhaps I should change it to "lilliana1269" for the future. Huehuehue.
Another username I've used once or twice is "~Trixx~". It has nothing to do with the old troll Trixx, I swear. (Although, we were good friends for quite some time.) It's my FH second account, and I've also signed up for sites using the spin-off "Trixx1289."
Sooo, yeah. Look for me as these usernames, haha! Except for the oldest ones, "katemaxo12" and that owl one. The sites I used them for are probably dead, and I never sign up with those usernames. Though, I could come up with a new owl one. . .
