My apologies; I grew up half and half between Marin and Fresno and that’s what I recall for both.

If I mistook where the term up north came from then I do apologize.

Edit: I think an issue was with my explanation. The people I know in both areas actually love it; people outside the area think they are stupid for living there. Therefore there is some appropriation of the pejorative.

Once again, if that’s mistaken in reference to Livermore then I apologize.
