This clip circulates online as a short, user-uploaded soundboard sound named for Kellogg's Corn Flakes, rather than as a verified clip from a commercial or cartoon. Its appeal comes from that instant food association: a burp after breakfast is a simple, universal joke that needs no explanation, which makes it easy to drop into memes, reaction videos and short-form edits. Because it lasts barely half a second, it works as a throwaway gag rather than a centrepiece, and it has stayed in use for quick, low-effort comedy where a gross, cartoonish finish is the whole punchline.
