劳资恋上你闺女了老娘缠上你儿子了
[láo zī liàn shàng nĭ guī nǚ le lăo niáng chán shàng nĭ ér zi le]
Roughly translated as 'I've fallen for your daughter, and I'm going to pursue your son,' it humorously suggests a scenario where the speaker is romantically interested in both a person's children. It can be a way of showing persistence and boldness.
