待你秀发及腰我咔嚓一刀
[dài nĭ xiù fā jí yāo wŏ kă cā yī dāo]
The translation 'Waiting until your hair reaches your waist and then chop it down' conveys a somewhat playful and whimsical expression. The phrase hints at cutting the person's hair once it grows out long and beautiful, perhaps reflecting an unconventional attitude.
