Squid Game is a South Korean survival drama that premiered on Netflix in 2021, with Season 2 arriving in December 2024. In the second season the players vote after each game on whether to stop or continue, pressing a red X to leave or a blue O to stay and chase a larger prize. Clips of that tense voting sequence spread widely on TikTok and YouTube, and the short O confirmation tone was isolated as a reusable sound for polls, decisions and mock votes online.
