Squid Game is a South Korean Netflix drama that premiered in 2021, created by Hwang Dong-hyuk, about indebted contestants competing in children's games for a cash prize. In the voting scenes players choose O to continue or X to end the games, and the X response became a widely copied reaction online. Clips of the vote spread on TikTok and YouTube as a shorthand for refusing something outright, which helped the short buzzer tone survive beyond the show as a meme sound for polls, edits and gaming videos.
