Cajun English. Some of these I only learned later in life were unusual. I still have a hard time imagining a world in which we don't say "why don't you get down with me?"
"Pass the mop" - mop/sweep the floor
"Come see" - come over here
"Save the plates" - put the dishes away
"Get down" - get out (of the car)
"Make groceries" - buy food
"Couillon" - an idiot
"Emmerder" - someone who's in everyone else's business. This is a verb in every other dialect.
And there are a bunch of extra names for all the animals too.
