Early in his career, on some forgotten talk show (perhaps it was David Letterman in 1990), Dwight Yoakam chatted with the host about his birthplace of Eastern Kentucky. Describing the earthen mounds that protected roadways from the elements, he used the word "berm." His interviewer was taken aback. Berm? That's a fancy word for a honky-tonk country singer, he said. Yoakam just laughed. He knew that only the precisely right word, not just "heap" or "ridge" or "barrier," would make his story sing.
