他是我老公所以别看她是我媳妇所以别动
[tā shì wŏ lăo gōng suŏ yĭ bié kàn tā shì wŏ xí fù suŏ yĭ bié dòng]
In a very direct tone, this states 'he is my husband so don't look at her, she's my wife, so keep your distance.' It implies possession and a warning to stay away, protecting what belongs to them, often used when a couple has a close bond.
