YEAH YEAH YEAHS (BalconyTV)

A heckler is a person who shouts an uninvited comment, usually disparaging, at a performance or event, or interrupting set-piece speeches, for example at a political meeting. A heckler is almost always regarded as unwelcome by the person with justifiable claim to be the centre of attention. The audience too may find the interruption an unwanted distraction; however they may sometimes find the interjection amusing or apposite.
