Shyster, n. Origin obscure.] One who does business trickily; a person without professional honor: used chiefly of lawyers; as, pettifoggers and shysters.-CENTURY DICTIONARY. When Terry McGurk hove the brick through the window of Froelich's butcher shop he did it casually, on general principles, and without any idea of starting anything. He had strolled unexpectedly round the corner from his dad's saloon, had seen the row going on between Froelich and the gang of boys that after school hours used the street in front of the shop as a ball ground, and had merely seized the opportunity to vindicate his reputation as a desperado and put one over on the Dutchman.
