贱人曾就是我我就是曾小贤
[jiàn rén céng jiù shì wŏ wŏ jiù shì céng xiăo xián]
A reference to a popular TV show where this nickname comes from, it describes someone who adopts a character or persona from the series. 'Zeng Xiaoxian' here can refer either to himself in an endearing yet humorous self-deprecatory way.
