我是屌丝不发光
[wŏ shì diăo sī bù fā guāng]
A rather self-deprecating username which translates as 'I am a nobody and do not stand out', reflecting possibly a lack of self-esteem or recognition. Here, '屌丝' is slang often used in China referring humbly or ironically oneself as someone common and non-distinguished. Inappropriate if taken literally or out of cultural context.
