\In`croy`a"ble\, n. [F., lit., incredible.]
A French fop or dandy of the time of the Directory; hence,
any fop.

Note: The name is said to have been given in allusion not
      only to the extravagant dress, but also to the frequent
      use of the phrase ``C'est vraiment incroyable'' (That
      is really incredible.).
