贱癌晚期以弃疗
[jiàn ái wăn qī yĭ qì liáo]
'Jian' here means vulgar or cheap; 'Late-stage cancer of being cheap' is a sarcastic expression indicating extreme self-depreciation where the net user feels beyond hope or redemption, hence chooses not to fix themselves. An exaggeration expressing low self-esteem or humorous self-criticism.
