Squid Game, the South Korean survival drama released on Netflix in 2021, opens with Red Light, Green Light, a childhood game turned deadly for its indebted players. The game and its announcements quickly became some of the show's most recognisable moments, circulating widely in short-form edits, reaction videos and memes after the series became a global hit. The wait-for-instruction line endures because it signals a pause loaded with danger, making it easy to reuse for suspense, awkward waits and dramatic reveals in unrelated videos.
