Do You Call It Stuffing or Dressing?

Apparently where your from determines what you call this Thanksgiving staple. Kind of like soda vs. pop

Since I'm from Missouri, I've always called it stuffing, but someone just blew my mind on Facebook and told me it's technically stuffing when you actually prepare it IN the turkey, and dressing when it's made separately!! Doesn't that make so much sense?! But, I've never applied that, since we've always made Stove Top, haha!
