It's a misspelling of Chyort, which was the name of the villain in the book Psychic Warrior, which was my favorite book way back when I started using it. (15 I think) Anyway according to the book it was the Russian word for "devil" so being the good little wannabe goth boy that I was, lol, I thought that sounded pretty damn cool and started using it on forums and in RPG's. By the time I realized I spelled it wrong I had like 10 different website accounts under the name and I liked it better this way so I never changed it.
