rhetorical devices - What's the term for when a phrase is slightly changed for effect?

What is the name of the rhetorical device of slightly changing a standard phrase?

Here is an example:

McDonald's Yuan Menu

The original word, "Dollar," has been replaced with "Yuan," giving the phrase a new meaning, but a recognizable context.

Here's another example:

Clean Air Guitar Act

The word, "Guitar," has been inserted into the phrase, "Clean Air Act."

A near identical question has been asked here, "Changing a quotation so that the original is recognised, but has been given a new meaning."

Here are the answers that were provided to that question:

• trope




• reference




• allusion




• pop culture reference




• play on a quote




• snowclone




• paraphrasing

None of these answers are good. Trope, reference, and allusion are very broad terms. More important, they don't actually describe the act of slightly altering a phrase, and instead are describing the mere mention of a phrase. Snowclone is not correct because a snowclone describes a template based on an idiom.
