Squid Game, Hwang Dong-hyuk's Netflix survival drama, returned for its second season in December 2024 with a new ritual: after each game the players vote, pressing O to stay or X to leave, and each press triggers a bright ding. Clips of the voting scenes spread quickly across TikTok and YouTube edits, where the O press became shorthand for choosing to continue. Creators lifted the short chime for decision memes, polls and versus videos, and it remains a compact way to signal agreement with the show's tense atmosphere.
