So did my dad, who was raised by his Irish parents.
My grandfather’s family were Scottish, and my grandmother’s family were Irish. When we were little, they called us their little ‘Tulla Tulla’s”. I finally looked it up and Tulla is a medieval town in Ireland. I think it’s called Tulloch now, according to a search of the name.
My grandfather called city dwellers ‘lowlanders or flatlanders’ and mountain people ‘highlanders’. I am descended from the original hillbillies of the Appalachians since the 1700’s. LOL
I use that one every once in awhile.. (flummoxed)
