I'm rather sleep-deprived, so I'll have to wait until tomorrow before participating in the large debate which I'm sure this will elicit, but:
I wouldn't use {jay'} when making a compliment. {jay'} is invective, not just emphatic. You're basically saying "Your mother bakes jinxed food, and this fills me with contempt."
When we say something is damn good, we're using a vulgar expression, but we're not using it invectively.
I doubt the average Klingon would find the damnation of gods particularly important (they're all dead, anyway), so it probably wouldn't be a part of idiomatic speech (although you never know).
However, if you wish to explain the Terran phrase, you might want to construct a relative clause using joH'a'/Qun, and pum/qIch/QeHmoH.

So, I've been wondering for quite some time now, how to express the DIvI' Hol "god damn". How to convey its essence in klingon..
Of course the question is: what does "god damn" exactly mean ? does it mean that "god damns whatever", or the one who speaks "damns/curses god" ?
Anyway, the way I *feel* this wonderful DIvI' Hol expression, if I wanted to say:
"your mother cooked this god damn food"
I would express it like this in tlhIngan Hol:
{Sojvam 'Igh vutta' SoSlI' jay'}
the only problem is that the element of "god" is missing from this sentence; but I believe this is indirectly being conveyed by the {'Igh}. when something is cursed, either god has done the "cursing", or a human through "god".
so, I think that by the proper combination of {'Igh} and {jay'}, we can express in klingon this wonderful english expression.
'ej DaH, rIn QInvam 'Igh jay' ! hahaha
