The excerpt I cited discussed "euphemism" and "dysphemism" (highlighted). That second term would tend to mean substituting a coarser name for the word you mean (an online dictionary suggests that a man says he wants "axle grease" when he really wants "butter.") The words substituted in the verses you are asking about tend to be more sly than euphemistic. I don't know if you could go so far as to use dysphemism to describe them. But it's worth considering.

It may not be the right answer, but I pulled a book off of the shelf and read several pages before typing in a possible answer to your query. Do you perhaps want to rephrase that last complaint? It was, after all, an attempt to answer the QUESTION.
