Q:

What does "his laughter usually at his own expense" mean in Chinese?

What does "his laughter usually at his own expense" mean in Chinese? I use Google 翻譯, its answer is "他通常在自費的笑聲", which is very strange to me.
Note: It is my first time to ask question here. If my question is not appropriate or needs to be edited, please let me know. Thanks.

A:

I think Original post meant, how do you translate, laughing at own expense.
An simple translation would be 笑自己 / 開(自己)玩笑
