My wife's from Lafayette. When I met her, a few of our mutual friends had nicknamed her 'Swampy' for her Cajun-speak. She's very smart and educated (Civil Eng. w/P.E. license) and her writing is nearly flawless, but sounded especially funny here in Denver, where most people have a total lack of accent. Ten years of living here has gotten rid of most of it, but not all. Whenever we go visit her family, it takes me a few days to catch on.
A ditch is a 'cooley'. 'Big Daddy' is more common than 'dude' or 'man' when addressing somebody. "Hey Big Daddy, can you winch my jeep out of the cooley?" "What's up Big Daddy?" I'm not that big (5'9", 180), and I don't have any kids.
