The constant, highly irritating background noise created by crowds of people, usually women (AKA "woo-girls") and usually as audience members at TV shows like "Oprah", "
Dancing with the Stars", "
American Idol" and "
The Biggest Loser", as they scream "WOOOOO!" enmasse.
Can be written "woowoozela".
WOOOOOOOO! We're wuwuzelas!
