Kantai Collection, also known as KanColle, began as a Japanese browser game in which players collect personified warships, and the destroyer Yuudachi became closely associated with the word poi as a playful verbal tic. Fans clipped the short utterance, shared it in edits and soundboards, and turned it into a shorthand reaction for cute surprise or sudden realisation. Its tiny length and instantly recognisable anime origin have kept it in circulation long after the original game scenes faded from everyday discussion.
