Unrelated, quick Klingon question that's been eating at me for decades.

When little I went to universal studios and saw the Star Trek show. Basically you film a short ep with some audience selected to dress up and act. The guy who was Klingon stole the show with a simple joke. Every single line he had (he was to speak gibberish I think, and make it sound Klingon and they put subtitles up) he simply barked something like "noo chak no, bimbo Joe!"

It was high comedy. Was it gibberish, or was he possibly saying something ?
