The vuvuzela became globally recognizable during the 2010 FIFA World Cup in South Africa, where its constant buzzing sound dominated many broadcasts. Although the horn was already associated with local football culture, that tournament turned it into an internet-wide audio meme. Since then, creators have used the sound to represent sports crowds, loud annoyance, or chaotic hype. It still shows up in reaction edits and prank videos because a single blast is enough to signal football energy and instant noise.
