长发及腰借我拖地可好
[zhăng fā jí yāo jiè wŏ tuō dì kĕ hăo]
Literal translation is 'Long hair reaching waist, would it be alright to lend me [hair] for mopping?'. This playful nickname might suggest someone has very long hair and makes a funny offer about its practicality, adding a touch of humor to a physical feature.
