Familienduell is the German version of the television quiz Family Feud, in which two families compete by guessing the most popular answers to survey questions. A wrong guess is met with a harsh buzzer, a staple of the format that audiences instantly associate with failure. Clipped from the show, the sound has become a handy reaction effect for German-speaking creators, who use it to punctuate quiz fails, trivia mistakes and playful arguments online without needing any context from the original episode.
