snob

n.势利的人 (来源：英语学习门户网站EnglishCN.com)

Snobs look down at their inferiors, but at one timesnobs looked up at their betters. The word  snob, the ultimate origins of which are uncertain, is first found in 1781 in the sense shoemaker, cobbler,?a regional and informal usage. The word is recorded around 1796 in a slang usage particular to Cambridge University, "a townsman as opposed to a gownsman.?Both senses may have fed into the sense first found in 1831, " a member of the ordinary or lower classes.?Along with this sense went another (1838), "a person without proper breeding or taste.?From these two senses arose the sense first recorded in 1848, 揳 person who looks up to his or her social betters and tries to copy or associate with them.?We can see how this sense could blend into the other familiar sense, "one who looks down on those considered inferior"(1911).

势利小人们都瞧不起不如他们的人，但有一段时间，势利小人只是羡慕地位比他们高的人。 Snob这个词最远的起源还不清楚，它第一次出现于1781年，意为“鞋匠，补鞋人”，这只是一种方言和非正式用法。1796年左右的记录显示，这个词有一个专用于剑桥大学的俚语意思，“与贵族相对应的普通市民”。这两个意思都进入了它第一次出现于1831年的“普通或低下阶层中的一员”这个意思。这个意思与另一个意思平行(1838年）：“没有良好教养和品味的人”。从这两个意思发展来了“羡慕地位高于他（她）的人并尽量与之进行联系的人”这个意思，第一次记录于1848年。然后，我们就能发现怎样又从这个意思中派生出了其它我们熟悉的意思，即“瞧不起被认为地位比自己低者的人”(1911年）

"snob is someone who judges all things, from shoes and dinner parties to love and beauty, according to their social rating" Tom Wolfe)
“势利小人就是衡量一切事情都从他们的社会地位出发的人，从穿鞋和晚餐聚会到爱情和审美”(汤姆·沃尔夫)
