待我长发及腰吓死贱人可好
[dài wŏ zhăng fā jí yāo hè sĭ jiàn rén kĕ hăo]
'When my long hair reaches my waist, I will scare the hell out of mean people.' This phrase mixes traditional beauty standards with humor. There's a playful tone expressing the wish for retribution upon individuals considered unkind or nasty, using the growth of hair as an exaggeration of a passage of time until some sort of justice or comeuppance comes about.
