Snooks.
An exclamation of incredulity; a Mrs. Harris. A person tells an incredible story, and the listener cries Snooks—gammon; or he replies, It was Snooks—the host of the Château d’Espagne. This word “snook” may be a corruption of Noakes or Nokes, the mythical party at one time employed by lawyers to help them in actions of ejectment. (See STYLES.)
