What does the term "neat" mean when ordering a drink?

The term "neat" refers to a drink that is served straight from the bottle, without any mixers, ice, or water. This method of serving typically applies to spirits such as whiskey, vodka, or rum, allowing the drinker to enjoy the full flavors and characteristics of the alcohol. There is a certain purity and intensity in drinking spirits neat that is appreciated by connoisseurs.

When ordering a drink neat, it is understood that the liquid is to be poured directly into a glass, often a short one, and consumed without any dilution or chilling provided by ice. This contrasts with other serving methods like on the rocks (with ice) or mixed with other ingredients. Therefore, the answer that indicates a drink served straight without ice or water accurately captures the essence of what "neat" means in the context of ordering alcoholic beverages.
