Back seat pimple popper 

Someone that stands behind another person and tries to give them instructions about how to squeeze a whitehead on their face.

I became very irritated when my mother stood behind me in front of the bathroom mirror as I was squeezing a pimple on my face. She kept telling me how to do it even after I told her to stop. I said, “Stop being a back seat pimple popper!”.
