I got my nickname due to the Chernobyl virus. I got it from a friend of mine, but because my system date was set a couple days ahead, it wiped my hard drive before it hit many others' (namely most of Korea). The reason I got the nickname is because I called my friends to let them know about it so they wouldn't get screwed. Because I knew all about it ahead of time they joked that I was the original coder of the virus. Thus I got to be known as cherny. Although it may not be that cool, it's sort of interesting...
Oh and the DJ part goes without saying...
