rodomontade (rod-uh-muhn-TADE; roh-duh-; -TAHD), noun:
Vain boasting; empty bluster; pretentious, bragging speech; rant.

Rodomontade comes from Italian rodomontada, from Rodomonte, a great yet boastful warrior king in Italian epics of the late 15th – early 16th centuries. At root the name means “roller-away of mountains,” from the Italian dialect rodare, “to roll away” (from Latin rota, “wheel”) + Italian monte, “mountain” (from Latin mons).
