BIY：buy-it-yourself

大家可能会说“当然自己买啦整天让别人付账这还像话么!”其实，BIY的意思并不是完全如大家所想的那么笼统，我们先来看一下它的英文意思和具体解释吧：

BIY：Purchasing the materials required for a repair or renovation that one has hired a tradesperson or other professional to perform.

China’s new middle class tend to buy their new apartments as shells, and then kit them out themselves. It is less DIY, however, than BIY: Buy-it-Yourself. New homes need fitting out from floor to ceiling, a job that only professionals can do.

从上面的内容中，我们可以知道，“BIY”所谓的“buy-it-yourself”是专门指装修(decorate)房屋时用的。这个新词看来就是来自于中国呢，就比如现在的一些80后的年轻人，比较倾向于自己购买装潢材料，自己动手装修房屋一样。
