There is no confirmed original video or character tied to this yucky vegetable soup clip, so it lives mainly as a reaction sound. Short food and parenting creators use the line to caption picky eating moments, lunchbox reveals, and intentionally gross cooking attempts. Its appeal is the universal, childlike disgust that needs no context. Because the phrase is so specific, it stands out from generic ew sounds, which helps it get reused in stitches and duets about school lunches and healthy eating fails.
