> Personally, I find it best to not be too concerned about the terminology

I second this. My experience is that some people know this terminology if they're actively learning or teaching the techniques, but most of the people I've worked with who know the techniques and apply them successfully don't know the terminology and use the word "mock" universally, so it usually creates more confusion than clarity to try to distinguish the different kinds of test doubles by name.
