天花乱坠

The original sin of business schools is boosterism.

商学院主要罪过是天花乱坠吹捧。

They're so lacking in confidence in the attraction of the games they televise that they feel they have to hype up with some hysterical commentator in order to get anyone to watch them.

他们对于用电视播映比引力太缺乏信心, 以至于他们感到必须要用一说得天花乱坠讲解员来做实况广播, 以便招。
