骚年不骚枉为骚年
[sāo nián bù sāo wăng wéi sāo nián]
A pun-filled phrase translating roughly to 'If a youth isn't wild (mischievous), it's not right for being a youth'. It implies embracing youthful exuberance and the idea that young people should make the most out of their energetic and unrestrained youth before growing up.
