你愿意嫁给我吗你愿意娶我吗
[nĭ yuàn yì jià jĭ wŏ ma nĭ yuàn yì qŭ wŏ ma]
Translates directly into marriage proposal phrasing but appears here used likely in playful manner referring both traditional roles interchangeably; showing openness regardless gender norms when approaching significant relationships seriously despite context being casual forum setting often where usernames selected less formally.
