也许他还不懂两个字念变质
[yĕ xŭ tā hái bù dŏng liăng gè zì niàn biàn zhì]
The literal meaning is that 'Maybe he doesn't understand these two words sound degenerate'. It expresses disappointment or disillusionment in relationships. This user may be talking about losing feelings over time when faced with love or friendship. Love at first sight can turn into estrangement; this is what '变质 (degenerate)' stands for in this name.
