What does "chaser" refer to in bar terminology?

In bar terminology, a "chaser" specifically refers to a non-alcoholic drink that is consumed after taking a shot of spirits. This practice is common among drinkers who want to mitigate the strong taste or burn of the alcoholic shot by following it with something easier to drink, like soda, juice, or water. The aim is typically to cleanse the palate or reduce the intensity of the alcohol experience.

While a strong alcoholic drink before a weak one may describe a variety of drinking practices or styles, it does not capture the essence of what a chaser is. Similarly, an accompaniment for a mixed drink can refer to garnishes or mixers but does not denote the specific action of following a shot with a lighter drink. Lastly, a cocktail with multiple layers does not relate to the concept of a chaser, as it speaks more to the visual presentation and technique used in drink preparation rather than the practice of consuming a shot followed by a non-alcoholic beverage.
