“Spit” 是“吐”的意思。这个短语的字面解释是“吐出来”，这是什么意思呢？请看对话：

    A. You seem unhappy. What is going on between you and Lydia?

    B. I can’t tell you now. I am very upset.

    A. Spit it out, man. I want to know the truth.

    B. We just broke up.

    Note: If someone chats with you and asks you to “spit it out,” he doesn’t mean for you to spit something out of your mouth. Instead, he wants you to tell him the truth or your real feelings about something.

    Similar English phrases are “out with it,” “get it out of your mouth,” “just say it” or “tell me now.” These are imperative sentences.

    On the contrary, when people say “hem and haw,” it means the person doesn’t want to tell the truth and hesitates to speak out.
