Stilly:

I believe in modern parlance, "yeehaw" is a single term, or word, if it is a word, which I doubt. More of an ungrounded expletive or enthusiastic ejaculation. But in any case.

Do you suppose it derives from the marriage of "gee" and "haw", port and starboard commands for mule- and oxen-drivers? Or is it a corruption of "Yahoo"?
