(noun)Or "bonyeu". An old politically correct swearing word used mainly in Quebec by the french canadians.Deformation of the words "Bon dieu"(good God),which were considered as swearing by the original french people that first colonisated Quebec, and thus were a little arranged.
Used when things go wrong or when you want to emphasis something and you don't want to say real swearing.
Random idiot: I just squashed your cat with my car, my dear french canadian.
French Canadian: Bonyenne!!!
