“He was edentulous, but all the other checks were fine.”
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.
