不知死活的疯女人死缠烂打的贱男人
[bù zhī sĭ huó de fēng nǚ rén sĭ chán làn dă de jiàn nán rén]
This provocative and confrontational username uses strong language, likely in jest or intentionally provocative, portraying two entangled but dysfunctional people - one crazed woman and one tenacious, less honorable man in a tumultuous relationship. Note: the term is quite vulgar in Chinese context.
