Just a quick question. What is "woo"? I have seen the word used here often. However, I have Googled and checked with Urban Dictionary, but all it has is hip-hop culture definitions. From observing its usage here, I understand "woo" to mean "hooey" or, more specifically, "paranormal blather" or "spiritual claptrap." Am I correct in this? If so, what is the etymology? Is it perhaps onomatopoeia derived from the sound a ghost is supposed to make, or might it be an acronym for something like "wild outlandish opinion"? Then there seems to be a repeated "woo woo" variant. Is the repeated "woo woo" the original, shortened for easy Internet usage? Is it possible that "woo" is the misinformation, and "a woo woo" is the misinformed? I will edit the replies into a skeptical entry for the Urban Dictionary. Thanks.
