The argument I'm making is that the reason we don't understand the gibberish from DS9 and elsewhere is because it is supposed to be considered canonically no' Hol, even the stuff that (coincidentally, I'm sure) sounds like someone doing a bad phonetic reading of modern Klingon words. The section on no' Hol (KGT p. 11-14) is written as if it's trying to reassure the reader that even if a Klingon says something that sounds like gibberish, it's actually perfectly acceptible as a contemporary use of ancient language. Okrand doesn't mention many examples of TV show gibberish specifically (though mova' 'aqI' ruStaq (KGT p. 13) is a line from "Looking For Par'Mach in All The Wrong Places" (DS9)), but it seems clear to me in retrospect that the digression on no' Hol was intended as a way to include all the TV gibberish in the canonical linguistic history without having to really make sense of it. Which is why I said earlier that all the stuff we've seen on TV and film has been incorporated into canonical Klingon, even if just as a more ancient form of the language.
