大姨夫把你媳妇带走
[dà yí fū bă nĭ xí fù dài zŏu]
In Chinese culture, "大姨夫" (Da Yifu) usually refers to the husband of one’s mother’s elder sister. However, this net name might be using it playfully in another context, saying something along the lines of 'uncle by marriage take your wife away.' This could imply a sense of humor, irony, or perhaps even jealousy.
