ranting: noun
a long, angry, and impassioned speech. “at times, his rantings would become incoherent”
adjective
speaking at length in an angry and impassioned way.
I’m more familiar with the definition that includes the length of the speech. If you were using a definition that only refers to the energy, then I wouldn’t call it hyperbole.
Fun fact, Trump ran for the Reform Party nomination, which eventually went to Pat Buchanan, back in 2000.
