This is a very brief slap sound effect, lasting just over three-tenths of a second, with a sharp, single impact and no dialogue. It feels sudden, cheeky and a little cartoonish, like a quick visual gag turned into sound. It comes from Jewelpet, the anime series, where the slap lands as a light comic beat.
