swig

This term conveys a sense of urgency or lack of refinement, often suggesting a casual or hurried manner of drinking. It is frequently associated with drinking directly from a container rather than using a glass, evoking an image of thirst or a desire for a quick hit of a beverage.

As a noun, it describes the specific action of the gulp itself. While it is a countable noun, it is often used in phrases like "take a swig," which emphasizes the singular, forceful motion of swallowing a large volume of liquid.
