pen robber
n.— «Spiriting public funds away, just like that! Leaving Nigeria dry, while pretending to be good Christians, moslems or gentlemen. “Pen robbers,” that’s what the public (the ever short-changed masses and impoverished elites) call people like that.» —“Looking back, to move forward” by Tunde Thompson Daily Sun (Lagos, Nigeria) Aug. 7, 2006.
