待我长发及腰热死算了
[dài wŏ zhăng fā jí yāo rè sĭ suàn le]
Translated to 'By the time my hair reaches my waist, I will be dead of heat.' On one hand, it expresses impatience while waiting to grow out long locks. And, on another level, humorously exaggerates extreme dissatisfaction with something unbearable (likely heat here). It mixes impatience and lightheartedness.
