i was very young and needed a name for Quake 1 I couldn't think of anything, so my dad thought of trying to think of something with my name in it
thus antimatter spawned
I used to type it antiMATTer, but now i use ANTIMATTER
that came to be because in Quake3, you can you colors in your name. So I made my name purple and capitalized, so when I pulled down the console it would stand out for me to see my kills
