The waka waka sound is strongly associated with Pac-Man, the landmark arcade game released by Namco in 1980. It became one of the most recognizable game audio cues of the early arcade era and stayed familiar through ports, sequels and pop culture references. Online, people use it as a shorthand for chomping, collecting items or moving through something in a playful way. Its staying power comes from how simple, catchy and instantly readable the sound is, even for viewers who have never played the original cabinet.
