Rhetorical questions are supposed to make a point, and I'm asking you what that point was.
Now my question is semi-rhetorical because while you could answer, it's pretty clear that your question was just a phrase you saw somewhere that you're trying to use as an insult even if it doesn't quite fit the context.
For the first part, the corpulent thing, I'm just pointing out something that's true. It's unusual to use the word figuratively.
For everything after that, it's because you're kind of being a dick.
