待我长发及腰勒死你可否
[dài wŏ zhăng fā jí yāo lè sĭ nĭ kĕ fŏu]
When my hair reaches my waist and I strangle you with it, will you accept that? It's an extreme expression, using imagery to symbolically convey wanting to hold a close or controlling power over someone else when the person finally achieves a certain personal goal, often implying romantic intent.
