I have got to catch some Zs! 我要休息一會兒!

to catch some Zs: 休息一會兒

Since we are maxed out, we have got to catch some Zs.

Z:聯想-->卡通片中卡通人物在睡覺的時候,不就是用英文字母Z表示嗎?

外國人想象力倒還挺豐富的喲!

I am maxed out now, so I have got to catch some Zs!

Are you maxed out? Just go and catch some Zs!

Remember: Health is wealth!
