In anime fandom, poi is best known as the sentence ending tic of the ship girl Yuudachi in Kantai Collection, where it gives her speech a distinctive and easily imitated rhythm. Short voice clips of the word spread through soundboards, chat servers and video edits because a single syllable is easy to recognise and reuse. It sits alongside other catchphrase clips like Tuturu in anime sound collections. The clip remains popular for its brevity, letting creators add character and humour without interrupting dialogue or music.
