Hmm...Well, not much of a story behind mine, but I'll give it a go.
I was on the internet, and I found a username generator. No, it's not that simple. It gave me a nonsense name with Insanity at the end. Now, insanity is a word that many people have used to describe my antics. So later that evening I was in the kitchen talking to my dad and I thought, Silent insanity. And I tell him that would be an AWSOME username. Later I went on Kongregate.com and made an account under the name. As soon as I entered Ninja Chat, I got compliments on it. Several months later, I copied a link to a friend on Kong and she recommended this website. That's about all there is.
