In China, people tend to call “going Dutch” an “AA treat,” meaning dividing the bill equally among all the diners. But now “AB treat” has become a fad among young people as some males now choose to pay a bigger slice of the bill, say 70 percent, while female friends dining with them pay the rest.

在中国，人们把几个人平摊用餐帐单的行为叫做“AA制”。而现如今，年轻人当中开始流行起“AB制”，它的意思是说，外出用餐时，由男性来支付帐单的大头，比如70%，剩下的部分由女性来支付。

For example:

The dinner party last night was on an AB treat, so the ladies didn’t spend much on that.

昨晚的聚餐是AB制的，所以女士们都没有花太多钱。
