Do a snow job字面解释是“做雪工”，这是什么意思呢？请看对话。

    A: Ryan said I had done a snow job. What did he mean?

    B: What did you do to him?

    A: Well, he invited me to go fishing with him last weekend and I turned him down. I told him I had a business trip in Shanghai. That’s an excuse of course — I had a very important date, in town, in fact.

    B: Well, I guess he somehow came to know the truth. Perhaps someone saw you with your date and told him!

    Note: “A snow job” is a colloquialism for a cover-up, as you can literally “cover” things up with snow. When people “do a snow job on” others, they are telling a lie or using excuses to cover things up and make themselves look better. For example: Don’t try to do a snow job on me, I know all your tricks!
