This sound is associated with older episodes of SpongeBob SquarePants, where it plays during especially gross or unpleasant visual moments. Online, it became a handy reaction cue for meme edits because viewers immediately connect it with exaggerated disgust. It still shows up in short videos, reaction compilations, and low-effort comedy posts whenever a creator wants an unmistakable cartoon "ew" beat. Its staying power comes from how recognizable SpongeBob is and how quickly the clip explains the joke without any spoken setup.
