Squid Game, the South Korean survival drama released on Netflix in 2021, made its masked guards, pink corridors and strict checkpoints instantly recognisable around the world. The elevator identity check, tied to the Frontman and his masked staff, became a favourite clip for editors who wanted a quick shorthand for authority, secrecy and controlled access. Shared through TikTok, YouTube Shorts and meme pages, it crossed over into unrelated jokes, including Spider-Man edits, because the sound alone signals that someone has passed a hidden test.
