Gargling is the act in which one bubbles a liquid in one's mouth. It usually requires that the head be tilted back, allowing a mouthful of liquid to sit in the upper throat. The head can be tilted by extending either the neck or the back, depending on what is comfortable for the gargler. Air is then expelled from the lungs, causing the liquid to bubble and undulate throughout the throat and mouth region.
According to modern western etiquette, gargling is a fairly impolite activity during a social occasion or mealtime. It is typically performed in a bathroom at a sink so the refused liquid may be disposed of properly.
