Years ago, in Basic Training, one of my drill sergeants told us that the word was actually HUA, and was an abbreviation for heard, understood, acknowledged. Since then, I know of nonbody else who has ever heard this claim. Anyone here?

Thanks for clearing this up. Now that I see the word in print and your explanation, I know I was wrong, in thinking they were paying tribute to Oprah.
