Falutin

My daughter was in The Music Man recently and continues to watch the movie regularly, and I guess because the songs have worked their way into my subconscious, I described something as being "highfalutin." It's one of those words that everyone knows what it means but nobody really knows anything about. It is not from "highfaluting,"it can also be spelled hifalutin, and there is no lowfalutin or even a falutin. The dictionary says the word's root is the verb "flute," which verb I am not familiar with. I suppose the world has survived without gruntled or sheveled, so it can survive withut falutin too
