Some hunky guy who lost his shirt.

一个丢了衬衫的性感男人的故事。

Also, my father has never " lost his shirt" in a business deal -- he is too smart to lose all or most of his money.

不过，我父亲从未在生意场上失手过，他很聪明，不会输掉全部或大部金钱。

Other times my friend would simply " break even" -- he neither won nor lost money. But sometimes Bob would " lose his shirt" -- he would lose all the money he had.

其他时候我的朋友一般收支相抵(break even)，不赔不赚。但是有时，他会输的分文不剩(lose his shirt)。
