The Vietnamese word "phưỡn" means to swell or to distend. It is often used to describe a feeling of fullness, particularly after eating too much food.
In a more advanced context, "phưỡn" can also refer to anything that has expanded or swollen beyond its normal size, not just related to the stomach. For example, if you see a balloon that is overly inflated, you could say it is "phưỡn."
While "phưỡn" primarily refers to the act of swelling or distending, it can also metaphorically describe something that is exaggerated or overly inflated, such as a story or an idea.
To sum up, "phưỡn" is a useful word to describe the feeling of fullness after eating or anything that is swollen.
