Contrary to other beliefs, Square Head is not a reference to the WWII helmets that the Germans used. It is used in reference to the common shape in which many Germans heads are shaped. Dominating brow bones and a square jaw are what create this square look.
A literally translatedderogatory term used by French-Canadians to describe English-Canadians. But always spoken/written in it's French form. Can be used in a good natured way between friends. Kind of the opposite of "Frog".
Most English-Canadians are unaware of it's usage.
Word used by French Canadians (see Frogs, Pepper or Pepsi) to describe English Speaking Canadians.
The term Square Head refers to the way farm land was divided among the citizenry. The English had square farms whereas the French had rectangular strip farms stemming from a river. If you google map over Quebec and Manitoba you will clearly see the difference in farm shapes.
French Canadians used strip rectangular farms connected to a river so that more farmers can have access to water (more fair and productive). They find the square shape "stupid".
This is why it is an insult to call an English Canadian a square head...
