I don't have a problem with them blowing their horns, if they sounded cool. But during games I find myself in situations where I'm inadvertently slapping myself thinking there's an army of mosquitos around trying to devour me. It kind of ruins the game from a spectator's point of view. I think it's more or less tolerable in these early stages in the competition, but I can't imagine this will still be going on in a semi-final or final.
