待你长发及腰老子剪了卖钱
[dài nĭ zhăng fā jí yāo lăo zi jiăn le mài qián]
Translated, it means something to the tune of 'when your hair reaches down your waist, daddy will shear and sell it for money'. At first glance, it looks humorous and satirical, poking fun at situations wherein promises are made but actions taken against expectations later, or it could also be reflecting social pressure for monetizing certain attributes. It's unusual, drawing attention to itself possibly aiming for a laugh.
