sad sack

I have no use for the sad sack of a man.

叫他走吧，我不要这个不中用的人。

Think of Cyrano de Bergerac, who supplies poetry to the lunkheaded Christian to woo Roxane; or the movie Her, in which Joaquin Phoenix's sad sack falls in love with a computer operating system.

想想大鼻子情圣为呆头呆脑的基督徒写诗歌来追求罗克珊；或是电影《她》中，瓦昆菲尼克斯扮演的冒失鬼爱上了电脑操作系统。

Who is that sad sack mopping in the corner?

在角落里拖地的那个不中用的人是谁?

There is no room for such sad sack of man.

这里不需要如此一无是处的人.

He is such a sad sack man that he makes mistake everyday.

他真是个冒失鬼,以致他每天都会犯错误.

Are you a little tired of seeing the same sad-sack faces month in and month out?

每个月都看到同样一脸倒霉相的人,有点烦是 吧 ?
