The vuvuzela

The Tiny Plastic Horn That Will Ruin The World Cup:

If you've watched the Confederations Cup, you have no doubt been annoyed by the mysterious buzzing sound that drowns out even the TV announcers.
...
The sound is from the vuvuzela, South Africa's answer to the Thunderstick. By itself, it's just a small plastic trumpet that probably cost less than a dollar to make and creates no known musical notes. But when thousands of people toot them simultaneously, you get a loud, incessant hum that makes the entire stadium sound like it's being attacked by angry bees. It's a staple at any South African soccer match and ... surprise! Everyone hates it!
