Mansplaining is, at its core, a very specific thing. It's what occurs when a man talks condescendingly to someone (especially a woman) about something he has incomplete knowledge of, with the mistaken assumption that he knows more about it than the person he's talking to does. A common mistake.
A man who has seen a couple superhero movies gives a long explanation of Spiderman to a woman who has read all the comics and seen all the Marvel movies. He may be right, but she doesn't need the explanation, and his assumption that she wouldn't know the basics seems offensive to her. He has mansplained Spiderman to a comic nerd.
