The Vuvuzela is a horn about two feet long that produces a loud monotone tone.
It was made famous (or infamous, depending on your point of view) during the 2010 World Cup soccer games in South Africa.
The Vuvuzela produces a loud monotone note that has the ability to harm ones hearing if exposed to the incessant sound of many horns at close range as in a soccer stadium.
Vuvuzelas annoyed soccer players and fans alike, but spectators at the South African games blew into the tubular trumpets like there was no tomorrow, which, for the Vuvuzela, we hope there won't be.
The infernal noise from Vuvuzelas at the World Cup games in South Africa made it hard for athletes to communicate with each other or even concentrate during soccer games.
Man has three primal fears: fear of heights, fear of snakes and fear that Vuvuzelas will invade sports stadiums around the world.
