Joseph "Sepp" Blatter booed

In the 90th minute during the game Switzerland vs Honduras the face of FIFA president Sepp Blatter appeared on the big screen. He was instantly booed by the crowd in the stadium, as observed by this tweeter

Sifflé means "whistled at", or "booed".

Oh, well, I suppose his call to make the Welt a bötter place, or indeed my music video, has not yet reached the depths of the Amazon rainforest. Otherwise the audience in the stadium would certainly have connived at his (or FIFA's) corruption, tax avoidance and intimidation of governments.
