我是什么你是我媳妇
[wŏ shì shén me nĭ shì wŏ xí fù]
Literal translation: 'What I am is your wife.' This implies a claim on someone romantically. This could be literal (in a joking or serious context) where one asserts a marriage-like or close relationship status over another, expressing devotion or making claims of ownership or commitment.
