top-notch（adj.）
此外 top notch，“质量最好，最时尚的”，始于1840年左右的一个流行短语，由 top （形容词）和 notch （名词）组成。比喻某事物的“最高点”，但确切的机械形象不确定，并且似乎从未被提及。当时它是伞专利中的一部分的名字。
If a young blade drives his vehicle so as to pass others who are in his party, he is said to "tip them the go by."—If his dress consists of articles which are "all the rage," he is "quite the top notch." It is remarkable that these and similar phrases are most in use among people who claim distinction in the fashionable world. [Boston Weekly Magazine, June 12, 1841]
如果一位年轻的精英驾驶车辆以使超过团队中其他人，就称之为“tip them the go by"。 ——如果他的着装包括“all the rage”物品，他就是“quite the top notch”。值得注意的是，这些和类似的短语在声称在时尚界卓越的人们中最常用。[波士顿周刊，1841年6月12日]
Malgre the dislike of others to an extensive cultivation of cranial shrubbery, I consider long hair an honor unto a man, his glory and his charm. The beauty of the willow is its branches. Deprived of these and all its gracefulness has departed. The tassel of some vegetables is the top notch of their loveliness. ["Long Hair" in Rural Repository (Hudson, N.Y.), July 18, 1840]
Malgre 尽管他人可能不太喜欢种植头顶的灌木丛，我认为长发是男人的荣耀和魅力。柳树的美在其树枝。如果没有了树枝，它所有的优雅就都失去了。蔬菜的一些部位，如穗，是它们美丽的顶点。 [《乡村仓库》（纽约哈德逊），1840年7月18日]
