[tlhIngan Hol] New words from "Kauderwelsch"

[mayqel qunen'oS]

maltz:
> Most people say {qIvon}, though some say {qIvonDu'}.  Maltz says he has
> no idea why this expression has this slang meaning, given what he knows
> about his own {qIvonDu'}.

Does the above mean, that {qIvon} is another word for
{'InSep}/{qey'Hav}, and {qIvonDu'} comes into play because klingons,
due to bIraqlul have two of them ?
