Many years ago in a part of the South with a distinct French influence in the language, I got to know a woman who attended Notre Dame and had lived most of her life in the D.C. suburbs. We were in the car and stopped somewhere -- a store, a donut shop, somewhere -- and as I stepped out of the car I asked, "Are you going to get down?"
She laughed (as only she could) and asked if I were wondering whether she was going to dance. You know, get down.
Annoyed, I said, "No, are you coming inside??"
She still looked at me as if I had three eyes. We talked about it a bit, and I had to consider something I'd never thought about before. Then it struck me that one of the definitions of the French word descendre is:
descendre de = to step off [step]; = to get off [train, bike, horse]; = to get out of [car]
There are not a few other examples of French to Cajun French to English with that kind of result.
