I’m from the south so neither
I have never in my life said “yeehaw” by the way
I will say this, I managed to pick up a brooklynite inflection for asking questions for some fucking reason.
If you’ve ever heard a brooklynite ask a question like, “What are you a psychic or somethin’?”
They do this thing where they raise the pitch for most of the sentence and then on the last syllable they lower it back down. I do that sometimes. It’s weird.
