I'm from Nashville, TN and live in Seattle, WA and recall one particular instance on a date here when some girl was trying to get snippy & sassy about the "pen" vs "pin" issue. She and many other people here, and generally outside of the southern states, immediately equate the accent with ignorance. Which makes everyone adopting "y'all" more casually now really funny and weird to see, like are you mocking it or celebrating it?
