BIY：buy-it-yourself

大家可能會說“當然自己買啦整天讓別人付賬這還像話么!”其實，BIY的意思并不是完全如大家所想的那么籠統，我們先來看一下它的英文意思和具體解釋吧：

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.

從上面的內容中，我們可以知道，“BIY”所謂的“buy-it-yourself”是專門指裝修(decorate)房屋時用的。這個新詞看來就是來自于中國呢，就比如現在的一些80后的年輕人，比較傾向于自己購買裝潢材料，自己動手裝修房屋一樣。
