This sound is associated with Pou, the popular virtual pet mobile game that became widely recognizable through gameplay videos, meme edits and reposted short clips online. The brief “Naa” style vocal is remembered by players because Pou’s sounds are simple, cute and easy to reuse in edits. It still shows up in memes because it delivers a fast, harmless reaction beat that fits low-effort humor, nostalgic mobile game content and Spanish-language searches such as sonido de pou.
