The Grissin Bon sound comes from an Italian advertising jingle associated with the Grissin Bon snack brand. Online, the short melody spread beyond its original commercial context because it is catchy, specific and easy to recognize within a second. Meme editors and short-form creators began using it as a punchline for food jokes, retro ad parodies and abrupt cutaway gags. Its staying power comes from that contrast between polished commercial cheerfulness and the intentionally weird or low-effort visuals it often accompanies.
