The phrase comes from Brazilian comedian Diogo Defante and his Reporter Doidão persona, a deliberately unhinged reporter character known for absurd, high-energy bits. Fans clipped the biri biri chant from that material and shared it as a standalone reaction sound, where its meaninglessness became the joke. It spread through meme edits and short-form videos in Brazil, often dropped over moments that defy explanation. Because it needs no translation to land, it keeps working as a quick, instantly recognisable burst of chaos.
