在古代，皮革厂经常用尿液浸泡动物皮，而那些特别穷的人就把自己的尿卖给皮革厂，所以叫piss poor。这个短语是指“特别穷、穷掉渣、差劲的”的意思。

【例句】
Unhappy with the riches cause you piss poor morally.
对有钱人不满因为你实在太穷。

However, every silver lining has its cloud and the piss-poor finishing meant that our attacking best was wasted effort.
尽管如此，天有不测之风云，非常糟糕的把握能力却白白浪费了一场最佳的进攻演出。
