"Hubris: This is from the Greek word for "insolence" and means excessive pride. It's a tragic flaw—often the tragic flaw—and can bring about the tragic hero's downfall. You may see this "flaw" in Antigone (or not ... it's up for debate); but if you're looking for a classic example, think of Julius Caesar by William Shakespeare. When Caesar scoffs at the soothsayer's warning to "Beware the Ides of March," he is guilty of hubris in no uncertain terms."
He was using his body language and gesticulation to make a digresion and push the speach in a new direction for a brief amount of time. Digresion is commonly used in public speaking when one is giving and example, introducing new topic, bringin a guest in, and so on.
