The vuvuzela is a long, brightly coloured plastic horn traditionally used by football fans in South Africa, and it became known around the world during the 2010 FIFA World Cup, when its constant drone filled broadcasts from stadiums across the country. Clips of that distinctive buzz soon spread online as a shorthand for stadium atmosphere, celebration and noisy chaos. Short versions like this one are still shared in sports edits and memes because the sound is instantly recognisable even without any picture.
