pejorative nickname for the Canadian province of Ontario. Used mostly in regards to the the lack of soul people and places in Ontario posses. Compared to other provinces, where style, culture, and ingenuity play a dominant role, Ontario does not posses any of these qualities. Ontario is known for their anglo-saxon, conservative, overpopulated views, which diminish the respect even their own citizens have for each other.
