Continuing to converse with someone long after initially saying "goodbye". Most often occurs at the end of family gatherings in the South, specifically North Carolina.
"What took you so long to get home? I thought you were leaving your mom's house at three?"

"I know, I left at three, but I got caught in a Carolina Goodbye for 45 minutes."
