The exact recording behind this waaah clip is not clearly documented, so it circulates online mainly as a generic crying reaction rather than a quote from a known film or show. Short wailing sounds have long been used in cartoons and comedy edits to signal exaggerated upset, and this version spread through soundboards and meme videos because it is brief and instantly understood. Creators keep reusing it for fails, rejections and playful complaining, where a real cry would feel too heavy and a caption alone would miss the timing.
