The standing ovation comes from an ancient Roman military tradition

In ancient Rome, toast was added to drinks

Toasted bread crumbs absorbed the acidity of bitter wine and, in some cases, added flavor. Although the term "toasting" was not yet in use, the practice was common. Some say the Roman Senate decreed in the first century CE that all citizens must drink to the honor of Emperor Augustus before every meal, though scholars debate the validity of that claim. Eventually, the literal toast became associated with the tributes.

The art of classical rhetoric

Ancient orators snapped human communication in two: the open palm of persuasive rhetoric versus the closed fist of evidence-heavy dialectic. The former seeks to convince the many via one's speech, while the latter seeks the truth in an argument.

Loading the rhetorical canons in order was meant to help orators craft an effective and impactful speech.
