"Not Being Shameless is Wasting Youth": This nickname expresses the idea that youth should be bold and daring. There is a sense that if one doesn't push boundaries and embrace shamelessness in youth, it is considered a waste. It captures a rebellious spirit of seizing life to the fullest without worrying about social norms or reputation.
