SWIGS is an acronym for four different types of drinks: Drinks (6 letters), Nips (4 letters), Belts (5 letters), and Gulps (5 letters). Drinks are generally larger servings of beverages, such as a glass of wine or a pint of beer. Nips are smaller servings, such as a shot of whiskey or a mini bottle of wine. Belts are even smaller servings, such as a single sip of a drink. Finally, Gulps are the largest servings, such as a large gulp of a beverage.
