5-ish years ago in a game I play with friends which I won't mention. I've had the same name for abit and I decided "PotatoAI" wasn't really that good of a name so my friends and I helped out with thinking of names,and started like a small vote on it.
Eventually it boiled down to "Tiphius" "Iriquitious" "Esticica" and "Castia". Everyone was split between it so we spun a wheel for it.
It landed on "Castia". So yea,I've stuck with it ever since,it was something I felt unique about once. :x
And then there's "Earl Rickman",it was made because I had a friend that couldn't pronounce my name and just called me "Earl",and some friends joined in on it,eventually they made the "Rickman" just to trick new people that just joined the group into thinking that's my real name,and I liked it so much I have it on some other games I played where "Castia" isn't valid or already taken.
