U.S. [? alteration of FLINCH.] infr. To behave in a cowardly manner.
1893. E. B. Custer, Tenting on Plains, xxiii. 680. All the boys done bully, but Corporal Johnson—he flinked. The way he flinked was, to wait till the boys had drove the Injuns two miles, and then he hollered, ‘Gin it to ’em!’ and the boys don’t think that a man that would flink that way ought to have corporal’s straps.
