No it's not. I sported that title a while before I got my own custom title. It even became a running gag in our Kingdom of Loathing Clan, the Abandoned Archetypal Radical Gamer. Everytime someone who achieved that rank on this forum join, he/she gets his/her own rank as "Call me God" in the clan ranks.
There is even more titles beyond the "Call me God" one. The "10 Abandonia, 20 GOTO 10" is one of them...
