Years ago I was trying to think of a username for online gaming and other internet-type things that was concise, memorable, unique, and made a statement about me as a person. And also didn't have any numbers in it.
After a lot of thinking, I somehow came up with this one.
You say the letter names of the capital letters, and pronounce the lower case letters as one bit of the word:
Pee Que Ley R = peculiar. It used to be PQleeR, which is more accurate from a pronounciation point of view, but looks a little weird, so I added in the Y to form the name I eventually used. I even had an accent over the E at one point (PQléyR), but that was too complicated.
As far as I know, I'm the only person in the world using this name. A google search returns only my forum posts, youtube channel etc.
If you want to see what's so peculiar about me, I suggest you have a look at this
