Pac-Man was released as an arcade game in Japan in 1980 and quickly became one of the most recognisable video games in the world. The wakka wakka noise plays as the yellow character eats his way through each maze, and it has remained closely tied to the character ever since. As retro gaming clips, memes and remixes spread online, the short chomping loop became shorthand for eating, collecting and playful chasing, which is why creators still reach for it decades later even when their video has nothing to do with the original arcade cabinet.
