Squid Game, the South Korean survival drama released on Netflix in 2021, became a worldwide hit and turned many of its sounds into instantly recognisable memes. The wake-up alarm from the players' dormitory is one of those cues, often clipped and shared in short videos, edits and parodies that recreate the show's tense morning routine. Its popularity has lasted because the sound needs no explanation: even viewers who have not seen every episode recognise the cold, controlled world it represents.
