flagon-dry

Someone who abstains from tossing back steins of pale ale.

What is da difference between a recovering alcoholic and da large gossamer-winged insect dat eats mosquitos? Well, da soaring bug is a "dragon-fly", and da person is a "flagon-dry" --- i.e., he is now a teetotaler who never wets da inside of his fancy metal or glass tankard with strong drink, but instead just proudly displays it empty in his front window or on a shelf to show dat he's no longer using it for its intended purpose.
