Please give us the whole sentence and context where you saw the phrase. And what do you mean by "an emphasising idiom"?

Yes, this is an idiom.

Better to give more context, but you are correct. It means that someone stands up quickly, and is generally used to emphasise surprise or eagerness. No "jumping" need actually be involved....
