This practice probably originates with the expressionThat's what it's all about and may partly reflect implicit deference to the postmodern doctrine that every social artifact and activity can be regarded as a text subject to interpretation. But the usage is still too voguish to have won general acceptance;it is rejected by 59 percent of the Usage Panel in the example 这种用法现已被扩展到表示各种非语言作品和它所表现的事物之间的关系，比如在该政党大肆吹嘘他们的新官员 或 他的设计使用天然质地的原材料。 这种用法可能是源自这就是全部情况 的表示法，也许部分地反应了一种内在的区别：以后现代主义的观点来看，每一社会产物或活动都可视为需解释的一种主题。 但这种用法流行期太短暂而没有得到普遍的认可；百分之五十九的用法小组人员都认为下面的例子是不正确的： 〔rock〕A naturally formed aggregate of mineral matter constituting a significant part of the earth's crust.聚合体：构成地壳重要组成部分的天然矿物的聚合体〔methylcellulose〕A powdery substance prepared synthetically by the methylation of natural cellulose and used as a food additive, a bulk-forming laxative, an emulsifier, and a thickener.

Originally a rhinestone was a kind of rock crystal that was found in or near the Rhine and given a fancy name, as have other types of rock crystal such as Cornish diamond.Such stones could be made to imitate diamonds;hence the namerhinestone was applied to artificial gems made from paste, glass, or gem quartz.
