The chant comes from Squid Game, the South Korean Netflix series released in 2021, where a giant doll oversees the Red Light, Green Light game in the opening episode. In the Brazilian Portuguese dub, the doll sings Batatinha frita, um, dois, tres instead of the Korean original, and that version travelled widely through TikTok edits, reaction videos and game clips. It remains popular because the innocent rhyme instantly signals danger, making it an easy shorthand for a moment when everything suddenly stops.
