别闹呀你大爷的你是大爷的媳妇
[bié nào yā nĭ dà yé de nĭ shì dà yé de xí fù]
'Stop Fooling Around, You’re Supposedly His Wife' expresses mock exasperation mixed with sarcasm, possibly indicating an unruly person whom the speaker finds troublesome but also amusingly misbehaved, as if they should be acting more composed like a proper partner.
