Squid Game is a South Korean survival drama that premiered on Netflix in 2021 and quickly became a global phenomenon, with its games, green tracksuits and masked guards entering everyday internet culture. Its distinctive music and sound design were widely clipped, remixed and reused on TikTok, YouTube and Instagram, where the tone became shorthand for tension, danger and a contest with serious consequences. It remains popular because viewers recognise it instantly, even without seeing the show, and it can turn a simple edit into a high-stakes moment.
