Omaru Polka is a Japanese VTuber with Hololive Production who debuted in 2020 as part of its fifth generation, often shortened by fans to Omapol. Her streams built a following for loud reactions, singing and unpredictable comedy, and short voice moments like this Say, Dodonmai clip are clipped and shared by fans as soundboard reactions. The phrase works outside full streams because the delivery is so distinctive, letting editors signal a Polka reference in seconds even for viewers who only know her from anime and VTuber meme edits.
