>>War of Northern Aggression<<
I once made the error of using that phrase at a party at the Dean of Student’s house at a Boston University.
For the next two hours he brought various visitors over to ask me to repeat the4 phrase so they could discuss it.
That was already weird enough that I didn’t tell them the story of how our Baptist family was limited one swear word by Grand Daddy. He said “damnyankee” was alright to say because it wasn’t really two different words.
In the 1970s my Algebra II teacher would only refer to it as “The War Between the States” and when questioned would declare “There was nothing civil about it!”
