“我那破車太煩人了，只是蹭掉一點漆而已，竟然花掉我7000塊！”這樣的抱怨聽起來感覺怎么樣？嗯，我們知道那車一點都不破，而且挺值錢。炫耀自己的好車要這樣拐彎兒嗎？

Humblebrag, the combination of humble and brag, is the lowest, most despicable and loathsome form of self promotion, often delivered in one or two fragmented sentences on social media.
Humblebrag，就是humble（謙虛）和brag（吹噓、自夸）二詞的合成形式，即“謙虛自夸”，是一種最低級、最讓人鄙視、最令人厭惡的自我吹捧方式，通常以一兩個零散句子的形式出現在社交媒體上。

A typical and popular approach is to use a disingenuous complaint about something, a self-deprecating statement or a comment on something completely innocuous, as a vehicle to deliver the real message, which invariably shows the person in a favorable light. In fact it shows what an attention seeking and insecure person they really are. 常見的典型“謙虛自夸”手段就是通過對某事很虛無的抱怨、自我貶低式的言論或者對某個毫無關聯事物的評論來傳遞他真正想傳達的信息，而這個信息體現的肯定是他好的一面。事實上，這種謙虛自夸行為說明他們是極度需要關注、極度缺乏安全感的一群人。

For example:

Wow, I can't believe that a rubbishy little article like mine had been published in a national newspaper!
我真不敢相信我那樣一篇毫無價值的小文章竟然在一家全國性報紙上發表了！
