A chant used when someone is pleased, generally chanted in a deep growl over and over while banging your fists against something.
Suitable situations include after your team scores at a sport game, when you find a large amount of money on the ground, or during/after ejaculation.
The word originated when a group of school boys in the computer room of Newtown High School, Sydney, Australia, decided to play a stupid flash game on the willy wonka website instead of doing their science project.
