There is no confirmed original source for this clip, and it appears to be a generic user-uploaded sound effect rather than a line from a film, show, or game. Short, gross-out noises like this spread on soundboards and in short-form video because they are instantly recognisable and need no context to land. Creators reuse the watery retch as a shorthand for disgust, sickness, or a dare gone wrong, often in reaction edits and prank compilations. Its appeal is its brevity: one second is enough to sell the joke without making viewers sit through a longer, more realistic sound.
