mansplain

Essentially when a man assumes a woman (sometimes a man) lacks knowledge in an area where she (or he) is known to be an expert

Quite regularly, during team meetings in front of every else, when a woman who is reporting on her own project work with which she is most experienced with and has worked in the field for over twenty years, another peer always feels the need to "complete" her sentences mid-way, talks over her, hijacks her time to shine, taking over the explanations, progress report, issue deconstruction, evaluation, or review, thinking that even though they only have one fifth of the experience, knows little to nothing of her project work in detail, they must though have the knowledge to report on the woman's work better than she can.

To mansplain is for a man to talk to a woman in a condescending tone that implies the man thinks of himself as smarter or superior in some way to the woman which he is not. Some people will use this term unnecessarily when a point they made has been proven incorrect and they have nothing else to say, but this is not, in fact, the correct use of the word. It is only correct to say a man is mansplaining if they have interrupted a woman or is explaining something to her which she did not ask him to explain or she has more experience on. An argument is often not a correct time to use the term “mansplain”

To explain in a condescending, oversimplified, and often inaccurate manner, without regard to the fact that the explainee knows more than the explainer, usually done by a man to a woman.

Not all condescending explanations are mansplaining; the term does not apply when the man in question is indeed more knowledgeable about the topic than the woman.

Mansplaining usually occurs on the topic of sexism, feminism, or gender inequality, but not always. For example, a male programmer could mansplain coding to a woman, despite the woman having more qualifications and writing better-quality code.

Related terms include whitesplain, straightsplain, and cisplain. The overarching thread is someone privileged explaining something to someone less privileged, about a topic the explainer knows less about.

Explaining something but angrier and more condescending.

Mansplain is often referred to when someone extensively explains something that the other party already has knowledge of, often in a condescending manner. The term is a combination of the words "man" and "explain" due to the commonality of men doing this. However, it can be used more broadly than just with men. This term is a negative term and is usually used by women.
