浪啊烂
[làng a làn]
'浪' usually refers to 'play' with exaggeration and '烂' means 'ruined' or 'rotten'. Put them together with a sigh particle, they express the feeling towards excessive indulgence resulting negative effects, possibly indicating that someone has spent much time playing rather than focusing on practical matters, thus falling into an improper condition eventually. Though there are various interpretations according to different contexts.
