According to the Oxford English Dictionary, the world fugle is either (1) a slang term meaning to cheat or trick, or (2) a word meaning "to make signals." As an example of this second it offers Carlyle's use of fugle-motion in The French Revolution: "The French nation is of a gregarious imitative nature; it needed but a fugle-motion in this matter." Despite the OED, it is not clear if Carlyle means "cheat," "signal," or both [GPL].
