Nope you are wrong; I have hung around folks from the “north country”. I have good friends that are from Harrisonburg and Charlottesville. I have even visited those places. Or do you mean really up north, like Leesburg, Ashburn, Reston, or Fairfax?
Now I get the word “fack”. It reminds me of an aged joke, and there probably is a lesson somewhere in the joke for you, young grasshopper.
A young bull and an old bull stand on a hill overlooking a herd of receptive young heifers. The young bull says, “Let’s run down there and fack one”. The old bull replies, “No, let’s walk down there and fack them all.”
