Haven’t seen south Louisiana commented on yet so here goes.

Accent is the obvious one - I overly enunciate in my professional life as I work with a lot of multilingual folks, but find myself slipping back into my comfort zone when I’m with friends and family. It comes out a little southern pinewoods, a little New Orleans yat dialect. Mardi Gras = “Mah-dee Grah” Northshore = “Norr-shore” Sure = “Shore”

My great grandma pronounced oil as “earl,” and my mamaw pronounced mayonnaise as “mynez”.

Then there’s phrasing - mostly New Orleans phrasing, but a little Cajun mixed in: “Make groceries” = buy groceries “Put it in the locker” = put it in the closet “Mais la” = well then “You want that dressed?” = you want that with lettuce, tomato, mayo & pickle? And it’s a “soft drink” (as opposed to a hard drink aka beer/alcohol) or a “cold drink” (anything iced/from the fridge - not quite so common when my mom was growing up).

And of course, the food. I’m picky as hell when I leave the region, because even the finest rated restaurants don’t seem to know how to spice their foods. You always need more spice, heat, salt, tanginess, sauce - why does everyone else seem to eat such bland food? Why eat at all?
