...actually its a rap name. I used to let my bro's rap group record on my pc until the sound card went. I was originally Ty-Rant(Tyrant) which meant an evil ruler. I found out a bit later that someone had already produced an album and hasd that name...so I needed to change mine. Back to the old dictionary, I wanted to keep 'ty' at the beginning because those are the first two letters of my name.
Well, I looked at the dictionary and found a bunch of variiations under Tyran(with something on the end), they were all acts of killing or something. Finally I came across "Tyrannicide" which is a killer of a tyrant...lol, so I used it semi because someone had the name tyrant which made me have to change my name. So its like against that person.
