At first, I thought maybe she was saying "See Joe Rivette on my sweet bête and get me some sugar", bête (pronounced bet) being a Cajun French word we use for a beast of burden, like a donkey or a horse. I supposed that meant that Joe Rivette might have been riding into town for the fais-do-do on a horse, but then when I started really thinking about it, I thought maybe she was describing Joe Rivette as her "sweet pet," a term of endearment not really used in the Cajun culture. Sugar in "get me some sugar" means affections such as kisses or hugs.
