[tlhIngan Hol] {SorHa'} ? Of course.. But with jay' what ?

So, we have the word {SorHa'}, meaning "to speak metaphorically". On the other hand, we can't use klingon words metaphorically, because we always need to take them on their most myopic, strict, and narrow-minded meaning. But then, how is someone supposed to speak metaphorically ? With what jay' words ? Unless he says in advance {DaH jISorHa'}, and then continues to stretch the meaning of any klingon words he likes. But is that the case indeed ? qunnoq
