A shot glass is a glass originally designed to hold or measure spirits or liquor, which is either imbibed straight from the glass or poured into a cocktail . An alcoholic beverage served in a shot glass and typically consumed quickly, in one gulp, may also be known as a "shooter".
Shot glasses decorated with a wide variety of toasts, advertisements, humorous pictures, or other decorations and words are popular souvenirs and collectibles, especially as merchandise of a brewery.
