The bang
From The Oxford Companion to Spirits & Cocktails
(properly written “bang!”) is a class of mixed drink created, or at least identified and named, by American drinks writer John J. Poister (1924–2011), wherein the ingredients include more than one iteration of the same basic flavor. His Cherry Bang, for example, contains gin, cherry Marnier, kirschwasser, and maraschino liqueur. See kirschwasser, maraschino. A characteristic innovation of the disco drink era, the bang is occasionally still seen.
