抢我媳妇者断子绝孙
[qiăng wŏ xí fù zhĕ duàn zi jué sūn]
The phrase means 'May the one who steals my wife lose his offspring.' This carries a curse-like tone against someone stealing a loved one. It shows a deep level of possessiveness and protective attitude towards one's partner, using a severe wish for bad fate upon the perpetrator.
