To explain in a patronizing manner, assuming total ignorance on the part of those listening. The mansplainer is often shocked and hurt when their mansplanation is not taken as absolute fact, criticized or even rejected altogether.

Named for a behavior commonly exhibited by male newbies on internet forums frequented primarily by women. Often leads to a flounce. Either sex can be guilty of mansplaining.
The members of the equestrian community were unimpressed when Bob posted an essay that mansplained a solution to a horsy problem they were all well-acquainted with.

When someone "explains" something to another person about a topic they are already familiar with/understand. This is typically done in a condescending manner under the pretense that the speaker knows more about the topic than who they are speaking to, i.e. they are subordinate.
1) Explaining the rules of poker to a poker dealer
2)Repeating a point back to someone in your own way, even if they just said the same thing
3)Telling a person that you know more about something because of blank, even though they are a professional/have a degree in the field that you do not have

Sidenote: it is okay to know a lot about a topic and make this known in conversation, but assuming that you know more than someone else, not accepting if you are wrong, not accepting that they may simply be more knowledgeable, and/or doing so in a condescending manner means that you are mansplaining.

Note: this definition and examples were built together by both a man and a woman

Most believe this to be only a term used by feminists when they don't have a reply, however it is a term actually meant to explain with someone is patronizing or belittling your intelligence due to your gender.
We were talking about politics when he starting mansplaining things to me like I was in kindergarten, as if my gender means I have a lower iq

A term used when a person (usually a man) explains something to someone (usually a woman) in a way that is inherently condescending.

Often misunderstood as any time a man disagrees with a woman - thereby deeming it a sexist slur against men as it implies that any difference of opinion with a woman automatically makes him a sexist - it is about the context of what is being explained.

Thus, while whatever it is usually IS factual, it is insulting in its delivery.
Example: Two coworkers (one man, one woman) work in finance. They go to lunch. When the check comes, the male coworker slyly offers to teach her a "trick," then proceeds to explain how to calculate a 10% tip.

The female coworker might say, "He mansplained how to move a decimal."

To explain something in an unnecessarily long winded way, so as to dominate the conversation, and to make statements that are not based on facts, assuming that people will believe and agree with him because he is male.
"The recession was caused by the government because it spent too much money and people should look after themselves and not expect society to look after its members or its community... ad nauseam.
...Therefore its all womens fault."

Despite claims of superior strength in avoiding over-emotional reactions, when a man encounters even one iota of criticism of men on the internet, he must then mansplain why women suck by comparison or must be radical feminists.

Mansplain--to put women down in response to criticism.
Even though Mansplain only points out a specific aspect of what some men do but not in every context, explainerOrMansplainer and Wicker33 were so overcome by the inability to accept criticism and had to condescendingly mansplain how women must be either dumb; (ironically) unable to take criticism (derp!); or should be dismissed as radical.

Basically when a man explains something to a women and gets chastised for it. Seriously, you can't make this shit up if you tried.
Female "Women and Minorities can't be sexist due to prejudice + power!"
Male "Yes they can. Saying that one group of people can't be racist or sexist will make them actually racist and sexist. They will be able to get away with behaviors that would be deemed unacceptable if the opposite sex/race did it. That will ultimately turn the people who are sick and tired of being told they're the only ones that can be racist and sexist into Alt Right White Nationalists like Richard Spencer."
Female "Stop mansplaining to me!"
