This sound comes from the battle feedback used in Pokémon Generation 3, especially the Game Boy Advance era titles Ruby and Sapphire and later Emerald, FireRed and LeafGreen. Composers associated with those games include Junichi Masuda, Go Ichinose and Morikazu Aoki. Online, the cue spread beyond Pokémon clips because it instantly communicates a perfect advantage. Creators still use it in reaction edits, matchup jokes and gaming montages for that quick, unmistakable feeling of a move landing with maximum effect.
