You have no idea

A phrase used by people who have no comprehension of a situation that is passively put back on the others in the conversation and when asked to elaborate, cannot.. They say 'you' have no idea when they really mean 'I' have no idea.

How was the math test?

Oh, you have no idea.

That's why I asked. tell me about it.
