Nobody knows exactly where this 0.14-second clip came from; it surfaced on a user-generated soundboard tagged simply as eww, yucky slime, with a stray hotdog tag that hints it was first used over food content. Short gross-out clips like this spread because they are endlessly reusable: one wet splat fits any fail, prank or cooking disaster without needing context. It belongs to the same family of gross-out staples like the fart meme sound, tiny effects that creators keep in their rotation for the exact moment something on screen turns disgusting.
