隨口說說 的英文怎麼說?

[1] I wasn't being serious.[2] I didn't mean it.[3] That's just big talk.[4] You are just saying it.[5] All bark and no bite[6] all talk (and no action)[7] I was bluffing.

[1]跟[2]可以普遍用在很多情況, [3]常用在一個人慷慨激昂的說出某話, 卻只是隨便說說而已, 超好用. [5]是正統的美國成語, 形容一個人只會說不會做, 就像一隻只會叫不會咬人的狗.

all talk (and no action) = 只是說說而已，沒有行動

I was bluffing. = 常用在說者釋出善意說願意做某事，但只是嘴巴上說說而已，心裡頭根本不想做，如例句
