I know this means to try hard to please someone (to suck up? ), but I was wondering if it can be translated literally, meaning to literally fall. Here is the sentence I've got: "I’m amazed some of you don’t fall over backwards with your expensive cameras." (a man who hates journalists says that when they ask him questions trying to take his picture). It seems to me that he's talking about them losing balance and falling, but I'm not sure. He was probably being ironic or something.
