CNN writes: "More hated than daft football referees, the trumpeting vuvuzelas of the World Cup have become a stand-alone phenomenon.
The throaty buzz from the South African audience sounds like a cross between an angry swarm of bees and a dental drill. Historically, the classic vuvuzela was made out of kudu horn, but the ones you see on TV are simplified, plastic and, presumably, cheap.
Originally used to call people together for meetings outdoors, the instrument is now an aggressive statement during sporting events, kind of like a basketball air horn for footballers. But the truest measurement of vuvuzela obsession may be in web parodies."
