A shot glass, also known as a shooter or jigger, is a small glass typically used to serve alcoholic shots. Some popular synonyms for this glassware include a pony, thimble, nipper, or tot glass. These terms vary in different regions and countries. In Australia, a shot glass is referred to as a shooter or a worm glass, whereas the UK uses the term tot glass. In Japan, the term sakazuki, meaning "sake cup," is used to refer to shot glasses used for traditional Japanese sake. Although the size and shape of these glasses may vary, they all serve the same purpose of serving delicious, strong drinks in small quantities.
