Mundl, full name Edmund Sackbauer, is the gruff Viennese lead of the 1970s Austrian television series Ein echter Wiener geht nicht unter, played by Karl Merkatz. The character became a lasting cultural figure in Austria for his direct working-class speech and short temper. Short clips of his insults later circulated online as reaction sounds in German-speaking communities, where a single word can sum up disbelief at someone's behaviour. Trottl endures because it needs no setup or translation for fans who know the voice.
