snow frog 

An somewhat derogatory American term a French-speaking Canadian, generally a quebecois (person from Quebec). A pretty simple etymology, really; "snow", indicating the eastern Canada's cold, perciptation-heavy winters, and "frog", a derogatory term for a Frenchman. See also quebe.

Horace: That jerk with the Quebec plates cut me off, then swore at me in French!

Eustace: Damned snow frog!
