A word we didn't know a few short weeks ago -- and most wish they still didn't -- and now we see it everywhere. The latest Speccie has at least three mentions:
Deborah Ross, on the movie Ajami: "It isn't about teaching the world to sing in perfect harmony (minus the vuvuzelas, obviously)."
Simon Hoggart on the World Cup: "He [James Corden] is a human vuvuzela, making loud and meaningless noises, because he can".
And the cartoon above.
I guess, like the World Cup, it'll be over soon, this rash of vuvuzela-ness, and that it'll fade into unhappy memory, if not quite as rare as the phrase "England wins!", then at least a rarely-sighted metaphor, for anything loud and meaningless.
