The Vietnamese phrase "đã đời" can be understood as a way to express a state of having enjoyed something to the fullest or to the point of being completely satisfied. It often conveys a sense of indulgence or having a great time, especially in relation to activities like eating, partying, or enjoying life in general.
In more advanced contexts, "đã đời" can also imply a sense of completion or fulfillment in experiences. For instance, you might hear someone say: - "Sau khi đi du lịch khắp nơi, tôi cảm thấy đã đời." (After traveling everywhere, I feel completely fulfilled.)
While "đã đời" generally conveys satisfaction or indulgence, it can also carry a slightly playful or cheeky tone, suggesting that someone has truly enjoyed themselves, possibly to the excess.
