Problem understanding 私のにわか景気


The phrase in question comes from 「カタカナ英語と和製英語：最近の傾向を中心として」からの抜粋. The text
describes words in Japanese that appear similar to English words and are
written in katakana. I am having trouble understanding this:

> マイブーム(英語{えいご}で言{い}えば「私{わたし}のにわか景気{けいき}」の意{い}。

What specifically does 私のにわか景気 mean? It sounds like _My unexpected condition_.
But that seems like a strange translation.

Any help?




景気 is not just a condition but a (good) economic condition/climate. にわか is
"temporary". にわか景気 refers to a sudden but temporary boom in business/economy,
such as the Gold Rush.

私のにわか景気 sounds funny to me, and it's intentionally so. It's for showing how
the phrase "my boom" sounds weird to the Western ears. In other words, 私のにわか景気
_should not make sense_.
