看他不看我少年你演出
[kàn tā bù kàn wŏ shăo nián nĭ yăn chū]
It roughly means 'Look at him not looking at me, boy (or girl), you perform now'. There seems some irony embedded. It appears that this is chosen probably when facing certain rejection or neglect; hence, adopting this alias may signify a bold, defiant stance adopted under these circumstances. It encourages people to focus attention on oneself and not care whether someone else ignores oneself.
