Hayley教口語，“光打雷不下雨”用英語怎么說？

Full of talk that is more threatening or impressive than that which one can or will actually do.

說的比做的更具威脅性或更令人印象深刻

例：

He always threatens to call the police if I don't stay off his lawn, but he's all bark and no bite.

他總是威脅我說，如果我不離開他的草坪，他就叫警察，但是他就是光打雷不下雨。

John talks big about how much money he'll make someday, but he's all bark and no bite.

約翰吹牛說他總有一天會賺很多錢，但他只是說說而已。
