This sound comes from the online meme cycle around a Grubhub commercial that spread widely through reposts, remixes and ironic edits. Low quality versions became especially popular because the crunchy audio makes the ad feel even stranger and funnier out of context. It is still used in short videos and reaction memes as a shorthand for awkward corporate vibes, cursed dancing and uncomfortable ad energy, often in the same space as other abrupt meme stingers like the bruh meme.
