If you need a secret codebook to figure out which public statements of the President are clearly "hyperbole", and which ones are perfectly fine and true, he's failed at his job already.
The humiliation is the point, the point being to flaunt it.
When you call them out on it, they reply well it is not hurting anything (even if it is), and it is within my power aka my authority to flaunt it.

Of course plenty of philosophers of legal and social theory say be careful with flaunting it such as Machiavelli, but it can be argued it is a primal human social need even if this social need often leads to bad places.
¯\_(ツ)_/¯
In sum do not take their literal words at face value about hyperbole, one needs to unfocus in order to understand. What was the libertarian / reactionary / cameralism Peter Thiel said again at the Republican Convention, Trump take Trump seriously but not literally. Once again like you said fionwe1987 this does not make sense at the face of it, except it does. People who already like Trump often enjoy flaunting it and want to ignore any silly statements he says for stupid silly statements disrupt their joy, while the same stimuli to a person who dislike Trump is additional bitter taste sometimes extremely putrid nonsense that Trump says.
