   {flash in the pan}, a failure or a poor performance,
      especially after a normal or auspicious start; also, a
      person whose initial performance appears augur success but
      who fails to achieve anything notable. From 4th {pan}, n.,
      sense 3 -- part of a flintlock. Occasionally, the powder
      in the pan of a flintlock would flash without conveying
      the fire to the charge, and the ball would fail to be
      discharged. Thus, a good or even spectacular beginning
      that eventually achieves little came to be called a flash
      in the pan.

   {To flash in the pan}, to fail of success, especially after a
      normal or auspicious start. [Colloq.] See under {Flash}, a
      burst of light. --Bartlett.
      [1913 Webster +PJC]

   Syn: {Flash}, {Glitter}, {Gleam}, {Glisten}, {Glister}.

   Usage: Flash differs from glitter and gleam, denoting a flood
          or wide extent of light. The latter words may express
          the issuing of light from a small object, or from a
          pencil of rays. Flash differs from other words, also,
          in denoting suddenness of appearance and
          disappearance. Flashing differs from exploding or
          disploding in not being accompanied with a loud
          report. To glisten, or glister, is to shine with a
          soft and fitful luster, as eyes suffused with tears,
          or flowers wet with dew.
          [1913 Webster]
