骚年玩世不恭
[sāo nián wán shì bù gōng]
'Young and Reckless in Attitude Towards Life' indicates a nonchalant or cynical attitude towards life by a young individual. 'Sao Nian' in Chinese can sound like 'wild years' or can refer endearingly to naughty kids; both interpretations imply mischievous, perhaps irresponsible behavior.
