My username comes from my DevianArt account, but I don't remember how did I get the idea.
I just remember that it was a different username but it was already taken so I said: "Let's just change a few things".
And it end up being Niktushi. lol
My friends gave me the nickname "Rappe" on 1st grade and then I turned it into Rabbe and now it's Rabbecito just for the memes. Mostly I use Rabbe on other platforms like Discord etc.
When I first got a Minecraft account, I was very into chemistry, and I wanted a unique nickname. So, I came up with 'Minecraftium Sulphate', which I shortened to 'MCSulphate'. After playing for a while and joining some communities, I ended up being called 'Sulphate' by most, which is what I'm called on everything except here, since I cannot take that name.
First, I've came up with some random nicknames but I was playing league at the time and I really enjoyed playing Yasuo and I just added and removed some letter and shuffle them and that's how Artsyo was born xD
At some point in our life we decide to do something dumb, like clicking circles.
