Yummy is a 2020 single by Justin Bieber, built around a simple, repeated hook that made the word itself instantly memorable. The song's playful chorus spread quickly through short-form video and meme edits, where creators isolated the repeated word and looped it for comic effect. Because the sound needs no context, it works across food videos, fashion clips, thirst edits and reaction memes, and its upbeat, tongue-in-cheek tone keeps it useful long after the song left the charts.
