A wuwuzela: 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 "wuwuzela".
