Wobbuffet is a Pokémon character known for saying its own name, and that voice became instantly recognizable through the Pokémon anime and games. Online, the clip spread as a reaction sound because it is short, loud, and easy to time with a sudden visual entrance or punchline. It stays popular in meme edits thanks to Pokémon nostalgia and its unmistakable delivery. Creators often use it in the same reaction-heavy spaces as cartoon sounds and quick gaming stingers like oof minecraft.
