[f. as prec. + MONGER.] One who uses the ‘flash’ language.
1825. C. M. Westmacott, Eng. Spy, I. 395. How many jovial nights have I passed and jolly fellows have I met in the snug sanctum sanctorum! a little crib, as the flashmongers would call it, with an entrance through the bar, and into which none were ever permitted to enter without a formal introduction and the gracious permission of the hostess.
