Uncouth language can sometimes be creative, even delightful.

I remember my high school basketball coach, a former US Marine drill sergeant, would sometimes get apoplectic and come out with some stuff that made us laugh, involuntarily, at the *worst* possible time (i.e., when he most wanted to be taken seriously).

I can't think of a *great* example of his most creative expletive-coinage, but I do remember him telling us how badly he wanted us to beat a successful and upwardly-mobile coaching rival of his, calling the guy a "rat-bastard." None of us had ever heard the term before, so we all cracked up in his face, making him even more enraged.

(Coach was right to be jealous of the rat-bastard in question, by the way: He quickly moved up from Hillside High School to coach in college and in the NBA, and then on to a career in broadcasting --- Dick Vitale.)

Not from Coach Kelly, but a favorite curse I learned, I think, here in New Orleans about 20-25 years ago: "Eat shit and die!"
