人不犯贱必有缺陷
[rén bù fàn jiàn bì yŏu quē xiàn]
The name translates to 'If a Person Does Not Act Despicably, They Must Have Some Flaws.' This indicates self-deprecation on the owner's part as he sees acting mean as the only flaw free quality; overall suggesting a humorous self-awareness about their imperfections.
