Nya is the Japanese word for a cat's meow, and in anime culture it became a signature sound for cat-girl characters who sprinkle the syllable into their speech. Clips of that playful vocalization spread through anime edits, short-form videos and soundboards, where users search for the sound by its short, memorable form rather than by a particular show. Its appeal is its brevity and instant recognisability: in under two seconds it signals cuteness, mischief or affection without needing any translation. That is why it remains a staple reaction sound for anime fans, streamers and meme editors.
