This is a generic cartoon-style splat effect rather than a clip lifted from a known film, game or show, so its exact recording origin is not documented. Short impact effects like this spread through soundboards and editing packs because they are easy to drop onto any visual gag. The exaggerated wet slap signals a messy landing in a fraction of a second, which makes it popular for fail compilations, slime videos and animated memes. Its brevity keeps it reusable, letting creators repeat the joke without the sound outstaying its welcome.
