大姨夫带着大姨妈私奔去吧

A colloquial and comedic play on words using terms for relatives in Mandarin. Here, '大姨夫' (Da Yifu, uncle-in-law from mother’s side) and '大姨妈' ('Big Aunt', slang for period) are put together in an exaggerated manner suggesting these figures eloping, adding a layer of hilarity. This is often used humorously among young Chinese internet users referring nonsensical scenarios.
