wtf is that sound in the stadium ???

The 'angry bee' sound of the traditional south African Vuvuzela horn is said to be driving visiting fans, players and even the referee to distraction.

One English fan said "What's wrong with these people. I can't hear myself think. Where's the cheering, boos, ref cussing and chants. We've brought along our trumpets and drums - but what's the point?"
