Boastful or inflated talk or behaviour.
Early 17th century: from French, from obsolete Italian rodomontada, from Italian rodomonte, from the name of a boastful character in the medieval Orlando epics.
“I’m sick of his ‘best of everything’ rodomontade.”
“He’s total nonsense, a big bag of rodomontade.”
Rampallion (noun) (rare) (archaic)
A ruffian, a villain, a rascal.
Late 16th century; earliest use found in Thomas Nashe (d. c1601), writer. Origin uncertain. Perhaps from ramp + -allion, perhaps showing alteration of rascallion by association with ramp. Perhaps compare later ramscallion, rapscallion, tatterdemalion.
