A man who interrupts or speaks over her with overconfidence and cluelessness, to explain something that she already knows — indeed, something in which she may already be an expert — on the assumption that he must know more than she does. In many cases, the explanation has to do specifically with things that are unique to women — their bodies, their experiences, their lives. When men interrupt or presume to correct a woman who is speaking of her own experience or expertise, they are implying that she is ignorant, that she is incapable of having authoritative knowledge. They are saying, essentially, “Shh. I know best.”
