私は興奮して固唾をのんだ。

I held my breath in excitement.

吐いた唾は飲めぬ。

A word, once out, flies everywhere.

唾液が多く出ます。

My mouth forms a lot of saliva.

考えただけで虫唾が走るわ。

That makes me disgusted just to think of it.

その男が、自分は百万長者だとあのきれいな女の子にいったことはまるっきり眉唾だった。

The man's statement to the pretty girl that he was a millionaire was all eye-wash.
