“Poi” is closely associated with Yuudachi from the Japanese franchise Kantai Collection, where the character’s speech quirk became especially memorable among anime fans. Short isolated clips of the line spread through anime meme edits, fan videos and soundboards because the delivery is instantly recognizable and easy to use as a reaction. It remains popular because it communicates confusion, cuteness and comic timing in less than a second, similar to how fans use clips like Tuturu for character-specific anime reactions.
