拽拽拽拽拽拽拽你妹
[zhuài zhuài zhuài zhuài zhuài zhuài zhuài nĭ mèi]
This is a bit of playful slang that emphasizes stubbornness (拽 which literally stands for arrogant here) in a mocking way with repeated words for added emphasis. It's typically lighthearted rather than genuinely insulting. The final two characters can be understood either literally as referring to a younger sister or simply adding frustration or exclamation to the preceding word string.
