No Tomorrow is a phrase that is often used to describe a feeling of hopelessness or despair, as if there's no hope for the future. It can also be used to describe a situation where one has given up on life and no longer cares what happens. In some cases, it can be used to express an attitude of reckless abandon, where one does not think about the consequences of their actions. No Tomorrow can also refer to a sense of living for today and forgetting about tomorrow, as if there's nothing left to look forward to in life.
