I just wanted something better then Cu3 or Cue ball, in the gaming community people would always say "Hey C U 3" instead of queue (I played pool A LOT at one time and shaved my head during that time, hence queue ball was my nick name)....Then I got the chip BUG and I have always liked Jesters and Jokers, soooo Chipjoker, and I wanted a better name that people know what it was..
LOL, I've been wondering why you would choose a relatively rare copper ion for a screen name.
