1. 1/3 of a quote from Fozzy the Bear from the Muppets: "Wokka Wokka Wokka"

2. The sound Pacman makes as he gobbles up candy in the dark while listening to repetative electronic music and running from brightly colored incorporeal beings until he gets the EXtra special magic pill when he tries to get as close to all of them as possible, until it wears off and he has to go looking for another one.

Onomatopoeic representation of the sound generated by a Boeing-Vertol CH47 series Chinook transport helicopter.

Originally "wakka wakka wakka" as uttered by Fozzie the Bear of Muppet fame. Fozzie wanted to be a comedian. Unfortunately, he was terrible. The threefold utterance was part of Fozzie's act. The shortened version has gained usage as an expression of delight, exultation or lust (sometimes all at the same time).

The sound that Pac-Man makes as he moves across the screen, of course!

the appropriate thing to say if you are a stand-up comedian who happens to be a bear that wears a bow tie and a hat.

do not worry. no worries

The sound of Fozzie Bear's (a character from children's program The Muppet Show) chuckle.
