long drink
noun1
Idiomatic A relatively weak (low alcoholic content per volume) and voluminous mixed drink, typically containing lots of ice and mixer.
- Long drinks generally have more mixer than alcohol and are often served with ice and a straw. The terms ‘straight up’ and ‘on the rocks’ are synonymous with the short drink, which tends to be more about the spirit, which is often combined with a single mixer, at most.2008, Hamlyn, Hamlyn All Colour Cookery: 200 Cocktails: Hamlyn All Colour Cookbook, Hachette UK
