我要做你爸你乖女婿我做做你妈的乖媳妇
[wŏ yào zuò nĭ bà nĭ guāi nǚ xù wŏ zuò zuò nĭ mā de guāi xí fù]
This is an unusual phrase used to playfully suggest close family relationships in a humorous or affectionate way, but it can also be confusing as it doesn’t follow typical familial structures and could be seen as provocative.
