A term that originated from GameFAQs' God of War 2 board. It was coined by a
troll who went by the handle "alchemy60," and was thought to be a bastardization of the word "
cretin."
Since then, the use of the term has spread among many veterans of the God of War community. It is meant to be an insult to the dim-witted members of Gamefaqs--those who point out the obvious,
haven't done basic research before asking a question, etc.
Random Crewton: So, did they say anything about Kratos'
brother appearing in God of War 3?
Sensible Member (in slightly more polite tone): Non-
canon ideas are non-canon, GTFO crewton!
