With no credited source or original clip attached to the name, meuu spread purely as a shareable soundboard clip passed around in meme edits and short videos. It sits alongside the sad meow song and other exaggerated cat vocal clips that creators use as an instant emotional punchline. Because the wail is instantly readable without any context, it works for pets, anime-style reactions and everyday whining alike. That simplicity has kept it in rotation as a low-effort, high-recognition reaction sound long after larger meme formats fade.
