Nyanchu is a long running character from Japanese children's television, best known from NHK educational programmes where the cheerful voice and simple language are aimed at young viewers. Clips of the character are often reposted outside Japan as short meme sounds, and this unchi line spread because the word is easy to recognise and the delivery sounds cute even out of context. Japanese speakers immediately hear a childish poop joke, while other viewers hear a random adorable outburst, which has helped the clip survive as a reaction sound online.
