"Poyo" is strongly associated with Kirby, the pink Nintendo character, and many fans recognize it as part of Kirby's cute vocal identity. The phrase became especially familiar through Kirby anime and game culture, then spread through short edits, fan compilations, and reaction memes online. Because the sound is so brief and instantly readable, it remains popular in clips that need a quick burst of charm, softness, or playful irony without interrupting the pace of the video.
