Omaru Polka, known to fans as Polka or Omapol, is a Japanese VTuber with Hololive, where she debuted as part of the agency's fifth generation in 2020. Known for her mischievous circus-ringmaster persona and high-energy streams, her voice clips are widely shared as short reaction sounds. This go chant captures that playful momentum and has spread through fan edits, streams and soundboards, where it is reused as a compact hype cue rather than a full song or scene.
