姑娘灭了三妻四妾的男人
[gū niáng miè le sān qī sì qiè de nán rén]
In traditional Chinese families, one man could marry several wives. This netname is from a woman's perspective and expresses disapproval toward such a tradition by implying she would 'destroy' or overcome men who practice polygamy. It conveys a feminist stance or modern views against old practices.
