woo woo（adj.）
Derisive term for things deemed pseudo-scientific or superstitious, by 1971. Probably from the moaning sounds traditionally assigned to ghosts; compare goetia. It could also be applied in noun form to a superstitious person or to the superstition itself (e.g. "I don't believe that kind of woo woo.")
In 1930s-1940s it was a term indicating sex appeal, usually applied to women; it was perhaps meant to convey the sound of a wolf-whistle in print, though it became a spoken term with a different inflection. By 1952 it was used in sci-fi stories by author Sherwood Springer as a term for a kind of attractive android.
