菇凉为你倾尽所有咸森为你六亲不认
[gū liáng wéi nĭ qīng jĭn suŏ yŏu xián sēn wéi nĭ liù qīn bù rèn]
'Girl Gives All for Love, Even Alienates Everyone'. Here, ‘菇凉’ (girl) is likely an unconventional way to write '姑娘' (gu-niang) which literally means young woman/girl; and '咸森'(xiansen) seems like a playful spelling variation. The whole nickname implies complete dedication or selfless sacrifice towards love or for someone, regardless of how much social relationship around one gets affected negatively due to these extreme measures taken just because of affection involved.
