Explanation: Cicero's Philippics are a series of speeches made by Cicero criticizing Mark Antony, one of Caesar's former officers and a member of the coalition which avenged Caesar's death. Mark Antony had a reputation as a bit of a lowbrow fellow, apparently not wholly slander, while Cicero was the very symbol of the ultrarefined senatorial elite.
Regardless of your opinions on Cicero, he absolutely torched Mark Antony rhetorically, with the second book of Philippics being particularly damning in calling Mark Antony a brute, a savage, and worst of all, repulsively unmannered!
Cicero's speeches were so infuriating that Mark Antony had Cicero killed shortly thereafter.
