Here's the story.
My oldest username was some thing else. (I kinda forget.)
My bro and me shared it on this one site.
Then he made his own and it was Xbox650,
Once we started playing an online game, I thought I better use a different username.
So the username I started to use was Link650s.
Since we were Bros, I though it would be cool to have 650 at the end of my user name like his.
Some time later, we played a game that was four player on the Gamecube with friends.
You have to name your character, So I was thinking of a name.
My favorite letter is J, and I could not think of any thing,
so I went with JOJ. (Note, I say it all in caps, like this J-O-J

)
When I made the name, first thing I heard was "joj?"
I told them what I meant the name to sound like, but for fun they would call him joj some times.

I liked the name so much that I added 650s to it then,
made it my most commonly used username online.
