Is used by Canadians to describe the people of Ontario. People who are from Ontario, but relocated to other, more friendly and sincere provinces also use this term. Concisely connotes a province of people beset by fake-friendliness, and a mentality hellbent on conformity above all else and a general intolerance for anyone that is not like them. One who will smile to your face and bad mouth you behind your back. Also used to connote a bigot or someone who hates and bad-mouths Americans, but spends half their lives in the US vacationing and shopping.
> "Hey, where are you from?"
> "I am from Onterrible. But I left there and so am now allowed to have a personality."
