Is there a name for a type of phrase like "Let's go, Brandon"? For some context, NPR:
In this case, the phrase isn't actually about supporting a guy named Brandon. Instead, it's a euphemism that many people in conservative circles are using in place of saying, "F*** Joe Biden."
More specifically, I am looking for the name for a phrase like this that intentionally hides a seemingly unrelated deeper meaning behind the literal interpretation of a phrase. In this case, the hidden meaning is vulgar.
So far, it seems like it is a euphemism/minced oath. Perhaps this is also a form of irony?
