我非徐良为何犯贱
[wŏ fēi xú liáng wéi hé fàn jiàn]
Translated as 'Why would I behave badly if I'm not Xuliange', this might suggest a self-mockery or sarcasm based on some public character or story where someone behaves inappropriately but humorously acknowledges it doesn't pertain to him/her, possibly referring to an online persona or character named Xu Liange known for certain antics.
