待你长发及腰用来拖地可好
        
            [dài nĭ zhăng fā jí yāo yòng lái tuō dì kĕ hăo]
        
        
            Literal translation as 'Waiting until your hair grows down to your waist – shall we use it to sweep the floor?'. Playful sarcasm used to describe extreme situations or unrealistic fantasies about romance.
