The clip takes its title from Tenue de soirée, a French film whose dialogue has circulated in short audio form among French-speaking meme and soundboard users. The phrase itself translates as 'it's not necessarily serious', a piece of everyday French understatement that travels well even for listeners who only catch the tone. Because it is short, calm and instantly recognisable as a brush-off, creators keep reusing it as a reaction to minor failures, awkward situations and anticlimaxes, where a louder or more dramatic sound would overdo the joke.
