laysplain

When a person without technical or direct knowledge of a subject (a layperson) attempts to explain nuances of that subject to an expert. Simple examples would be an antivaxxer trying to tell a research biochemist how vaccines work, or a flat earther telling an aeronautics engineer how physics proves NASA faked the moon landing.

You tried to laysplain Star Wars to Natalie Portman, she was literally in those films.
