A: Richard invited me to have dinner with him last weekend but I turned him down.

B: What was your excuse?

A: I told him I had a business trip in Shanghai. That’s an excuse of course — I had a date in town in fact. Then he said I had done a snow job on him.

B: He should have seen you when you were dating and knew you deceived him.

Note: A snow job is an effort to deceive, persuade or overwhelm with insincere talk. This slangy expression, originating in the military during World War II, presumably alludes to the idiom “snow under,” which means “to cover or bury someone or something in snow.”
