Woo-woo is a slang term used to describe those who believe in phenomena that lacks substantiated evidence to prove the claim of the phenomena. It can also refer to the explanations for the specific phenomena itself. It also describes the method a person uses to understand such phenomena, based on the subjective nature or their personal philosophy which can be neither proven nor disproven. In this sense, one could associate woo-woo with philosophy, religion, or any other branch of study concerning itself with knowledge that is open to interpretation or subjectivity.
Can you believe the woo nonsense that the woos are spouting out these days? Especially the woo-woo about ghosts! Everyone is believing in woo at the drop of a hat!

A cocktail composed of 25 ml vodka, 25 ml peach schnapps and 50 ml of cranberry juice. Served on the rocks in a highball glass. Can be served with a lime wedge as garnish, but only if aesthetic value is necessary. The perfect cocktail for getting wasted quickly, as the peach schnapps neutralises the bitterness of both the cranberry juice and the vodka, leaving an extremely smooth, cool and highly alcoholic beverage. Enjoy.
You want to get shit-faced fast with a decent tasting, highly alcoholic beverage? You drink a Woo Woo or three.

The Sound/Action a man performs when walking past his girlfriend after showering.

Action is performed by removing ones towel, thrusting of the pelvis to make ones penis perform a motion reminiscent of a pendulum, paired with a vocalisation of the phrase "woo woo".
