握不住的他不如潇洒扬了它扎心尖的刺不如勇敢拔了它
[wò bù zhù de tā bù rú xiāo să yáng le tā zhā xīn jiān de cì bù rú yŏng găn bá le tā]
Literally this nickname says 'if I can't hold onto him, then I'd rather just let it go as if he is dust in my hand; if it’s thorn sticking on my heart, better to be brave and pluck it out bravely.' It depicts someone's decision to stop clinging to things (or people) beyond their reach and choosing to boldly sever attachments that hurt them.
