The following quote is from the movie Coach Carter. The basketball team is in a locker room after a game they lost. They're arguing with each other and one of them says:
We had nothing but 32 points. I got 12 of them. What did you get, Kenyon?
Another team member answers him:
Just shut up, dog. The Crane swooped down on you and delivered a basket of beat-down. He clowned you, dog.
What does swooped down on you mean here?
