Ironic that question is being posed by crispandrefreshing!
There are a lot of arcane usernames, so I don’t know why you’re asking me rather than
mobico,
popa bar abba,
patur aval asur,
akuperma,
writersoul,
square root of 2,
or a lot of others.

and see the link posted there.
In answer to your question, though, click my username and check the URL. You’ll see that my name was originally different. IT got changed; I don’t know why.
