你长发及腰我咔嚓一刀
[nĭ zhăng fā jí yāo wŏ kă cā yī dāo]
'Your Long Hair Reaching Waist Length; I Snip Once.' This humorously refers to the act of abruptly changing someone's appearance by cutting their cherished long hair without prior warning or preparation, possibly hinting at abrupt changes made without consent or forethought in relationships or personal matters.
