骚年封心锁爱菇凉无心无爱
[sāo nián fēng xīn suŏ ài gū liáng wú xīn wú ài]
This nickname describes someone who has closed off their heart from love (literally 'locked up heart'), possibly as a result of past disappointments in love or romantic relationships. The word 'girl' (菇凉, also written as '姑娘') emphasizes that this person used to be open but now feels incapable of love.
