Actually, I tried to "pursue" the meaning of qIvon. Maltz seemed a little reluctant to talk about it. (I'd say "embarrassed," but that word is entirely inappropriate to use in describing a Klingon.) (MSN 1997/06/29)

taQbang ghIm is the basic structure. You can, of course, substitute turmIq or qeQ in for taQbang if that's what you really want to say. So you can say things like DaH jImej. turmIq vIghImnIS.

Maltz said Klingons don't have euphemisms for this sort of thing. On the other hand, there is a slang expression or idiom that's used from time to time, though mostly (but hardly always) by or to kids: qIvon belmoH (as in DaH jImej. qIvonwIj vIbelnISmoH. and the like). You might ask a child who's a little jittery belHa''a' qIvonlIj?

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'.

As with idioms in general, you can't substitute one word for another (unless you're playing word games). So saying something like qIvonwIj vIQuchnISmoH could only refer to making your qIvon happy, assuming it's possible to do such a thing.

There are also various slang terms/expressing be randy, horny:

• Huy - be spicy, be piquant, be hot
  
• jIr qIvon - the qIvon twirls
  
• roSbe' - does not lick/use the third toe
  
• wamtaH - hunting
