What's the story behind your nick name?

My forum nickname comes from when a friend back in school used to practice Ninjutsu and he would be all about his teacher he called Shidoshi. He also said that ninjas did all kinds of awesome stuff.

I simply robbed the name idea when I was out of creativity for a character name when I first started RagnarokOnline.
It was also my BETA cleric's name (I lost that account's information somewhere along the way).

I've been using Shidoshi for quite a long time now.
