Only from the war. It's a Geordie term and mainly used in football parlance.
Geordie is a term used by the whole of the UK. If you don't follow football or come from the Northeast you probably have never heard of the term.
I have been inoculated and have redirected my love to the Magpies. At least when they play like a team they do well on the field. I have to admit that I originally was interested in Yorkshire for family reasons but from a historical point of view Newcastle and much of Northumberland is so very interesting.
