arriviste

1.Boasting about size may be poor form and the sign of an arriviste.

吹嘘规模或许并非得体的行为，也是暴发户的象征。

2.How delightful to find an arriviste underling of 53 and a slacking boss of 70 in a thrusting, ageist industry such as investment banking.

在投资银行这样一个冲劲十足、歧视老龄的行业，找到一个野心勃勃的53岁下属和一个泄了劲儿的70岁的老板，是多么令人欣喜啊。
