贱得有出息骚得够洋气
[jiàn dé yŏu chū xī sāo dé gòu yáng qì]
A self-deprecating play on confidence. While literally translated as being worthless but still managing to do well, and being unconventional and modern (even hip), it's used ironically to show off or make fun of oneself for having character traits outside traditional norms.
