The clip is tied to PewDiePie, the Swedish YouTuber known for energetic gaming commentary, and to PUBG, the battle royale game that dominated streaming in the late 2010s. Short eating and reaction noises from his playthroughs were clipped by fans and shared on soundboards, where this muncher sound became a quick shorthand for greedy or messy eating. It remains in use because it is instantly recognisable, very short, and easy to drop into gaming edits, food jokes and reaction videos without needing context.
