WORD ORIGIN
late 17th cent. (originally a conjuror's word): by jingo (and the noun sense) come from a popular song adopted by those supporting the sending of a British fleet into Turkish waters to resist Russia in 1878. The chorus ran: “We don't want to fight, yet by Jingo! if we do, We've got the ships, we've got the men, and got the money too”.
