The Vietnamese word "phệ nệ" is an adjective that describes someone who is corpulent or plump, especially around the waist. It is often used to refer to a person who has a round or chubby appearance.
In more advanced discussions, "phệ nệ" can be used metaphorically to describe things that are large or abundant. For instance, you might say a dish is "phệ nệ" to indicate it is hearty or generous in portion.
