Here's why it's unlikely to have a real-world origin:
* No historical or linguistic evidence: There's no record of "Kalabunga" being used in any language or culture before its appearance in He-Man.
* Invented for comedic effect: The show's creators likely chose the word for its humorous sound and lack of meaning. It served as a catchphrase for He-Man's loyal companion, Man-At-Arms, who often used it in a playful, energetic way.
In short: "Kalabunga" is a fictional word, created specifically for the He-Man cartoon. While it might be fun to speculate about its potential origins, it's best to acknowledge that it's simply a made-up word that has become iconic thanks to its association with the show.
