The definition of the word NORDIC:

A person being from the Nordic countries, the northwestern European countries of Scandinavia (Norway, Sweden, Denmark), as well as Iceland and Finland.

-OR-

If you are of Nordic race: "a physical type characterized by tall stature, long head, light skin and hair, and light-colored eyes"

And I believe they all wear these types of helmets in NORDIC countries...

Or maybe it is just large busty women who sing operatic high notes...

Usually accompanied with long blonde braids...
