Poyo is the main vocal sound made by Kirby, Nintendo's pink hero, who communicates almost entirely through that word across games and the Kirby anime. Fans clipped and pitched the cuter, sadder takes into short reaction sounds, and sad poyo spread through soundboards, Discord servers, and short video edits. Its appeal is that it needs no dialogue or translation to read as disappointment. Even viewers who have never played a Kirby game understand the drooping tone instantly, so creators keep reusing it for wholesome fails and mock-tragic moments.
