The vuvuzela is a long plastic horn popular with football fans in South Africa, where it was blown in stadiums long before it reached a global audience. It became world famous during the 2010 FIFA World Cup in South Africa, when its constant buzzing filled broadcasts and sparked debate among players, commentators and viewers. Clips of the sound spread online during the tournament and kept circulating as a meme for noisy crowds, football celebrations and deliberately annoying interruptions in videos and streams everywhere today.
