vuvuzela
A trumpet-shaped horn, now usually plastic, that produces a loud buzzing sound.
When the Manchester United squad walked through the arrival gates at Durban International yesterday, most players heard a vuvuzela for the first time.
Where it comes from
Borrowed from Zulu vuvuzela (“to make a vu vu noise”), from the /vuː/ sound the horns make.
