Ah.
So I first registered on YouTube with a name that's probably worse than anything even Chillah posted. Brace youself.
I remember not really doing anything as that, and also lacking a profile picture. My next list of usernames is fortunately not as bad-
>RedCreeper10 (the obligatory Minecraft username)
>
was a variant I used as my actual Minecraft username until recently, since RedCreeper10 was obviously taken already.
Then we have:
>SkyDoesLer (a pun on SkyDoesMinecraft based on my real name, which you can probably guess from that. I continue to use it on Wiimmfi, but only there)
>The Emerald Gamer (I have a Steven Universe OC called Emerald.)
>96 Exits (o h m a n)
Ironically, I used my one name change on Wikia to switch from RedCreeper10 to 96 Exits, so my forum names for the two sites have swapped appropriatenesses.
And now for the "modern" names.
>ThatPlanet (My current YouTube name, as well as for various other things. Comes from "I want that planet to die.")
>ThePicklesDill (Only ever on iFunny, which I no longer use because a large portion of the user base hates another large portion, and I am part of one. Had a "festive" variant, 'TheMistletoeDill'.)
>SpongecakeSoup (I believe I've phased this one out)
>MrMrMMANGOMILK (In-joke between a few friends of mine. These are the same guys that made up SkyDoesLer. Used for my Skype, FanFiction.net, and I think my Discord maybe.)
That's currently all, until I go through another online identity crisis. I have a few more, but they're site-exclusive and bad.
