WOO
WOO is an exclamation of excitement, approval, or enthusiastic celebration
What WOO does
WOO is the sound of enjoyment becoming audible. The WOO at a concert, the WOO at good news, the WOO at 9am on a Friday: it is enthusiasm that has overflowed containment.
WOO as literary candidate
WOO's phonetic simplicity — one syllable, entirely vowel at its heart — makes it an ideal vessel for celebration. It is easy to produce loudly. This may explain its persistence.
