The tendency of some men to mistakenly believe that they automatically know more about any given topic than does a woman and who, consequently, proceed to explain to her- correctly or not- things that she already knows.
Woman A: When he started mansplaining to me what it really meant to be a woman in the 21st century, I got up and left.

Woman B: Really, what else could you do?

A sexist term used by misandrist women to disrespect, belittle and devalue the opinion of her male peers in an attempt to make herself appear smarter or better in comparison.

This is common among mixed gender discussions and debates. The term mansplaining is commonly thrown around by those wish to turn the argument into a battle of the sexes or just lack any knowledge or means od adding value to the discussion and wish to devalue the input of other's (in this case males) who are involved in said discussion.
Sue: "I think WWII was hardest on wives back home then the solders."
Bob: "What about the men serving who put their lives at risk during WWII? I think it was harder on them knowing they might die and not see their wife again."
Sue: "Oh there you go again mansplaining!"

Originally, this term was used to describe boorish men who felt the need to "correct" what a woman said, even on topics that the man didn't know anything about.

However, the term quickly degenerated into a get-out-of-jail-free card used by angry women when a man dares to point out even the most blatant error.
Old: That Bob is trying to tell Jill how to raise a horse? She's raised championship thoroughbreds for decades and he's never even ridden a horse. What a stupid mansplainer!

New: OF COURSE HAMSTERS KNOW HOW TO SPEAK IN RUSSIAN! STOP MANSPLAINING!

What a man does when he assumes that most of the women he talks to need to hear his explanations. The problem is not the explanation itself but the underlying and often unconscious belief in inequality, the systematic assumption that women are not very intelligent, knowledgeable or competent. Mansplaining is always talking down, a form of condescension. It can be done with contempt and scorn or with benevolence and generosity, the way a father may explain something to a child. It can also be part of an attempt to impress a woman, like any other show of strength, competence, skill, money, cojones or bravery.

How can you tell that a man is mansplaining?
– It is most obvious when a man who knows little about something explains it to a woman who knows a lot about it, like when a layman attempts to explain how the brain works to a female neurosurgeon.
– When a man doesn’t attempt to find out how much a woman knows about something before explaining it to her.
– When a man disregards evidence of her competence to continue his explanation more than once.
– When the explanations are unsolicited, uncalled for or otherwise inappropriate.
– When he continually cuts her off to continue his explanation.
– When he explains her thoughts, feelings and behavior to her despite her objections.

When a man treats both men and women this way he is not a mansplainer per se, he is simply an entitled ass with an inflated ego who believes humankind stands to benefit from his knowledge.
I get tired of the guys in the tech department mansplaining me.

A term created by radical feminists to automatically discredit the opinion of a man because he's, well, a man. See also Feminist Shaming Language.
Man: I think your argument about women being oppressed by an evil patriarchy is wrong because of x, y and z.

Feminist group: Oh look, mansplaining from a member of the male species! How dare you interrupt our bitching session with your facts and logic! Let's get him, sisters! Make jokes about him having a small penis, that'll show him!

Attempting to explain away making sexual passes on a young lady when you're a married professional in the comics industry, aka Brian Wood. Afterwards you continue to go on and act like you're a feminist and really respect women.
Mansplaining - Tess Fowler is correct about this: I did make a pass at her at SDCC Hyatt bar roughly 8 years ago. But when she declined, that was the conclusion of the matter for me. There was never a promise of quid pro quo, no exertion of power, no threats, and no revenge. This was at a time in my career when I had very little professional power or industry recognition. The pickup was a lame move, absolutely, and I’ll accept the heat for having done it, but that’s all it was: I liked her, I took a chance, and was shot down. I immediately regretted it, and I apologize to Ms. Fowler for the tackiness and embarrassment of it all.

I’ve kept quiet for these last couple weeks because this is a problematic thing to address without unintended blowback. While I believe she is as incorrect as she can be about what my intent and motivations were, I don’t want to encourage any negative opinion directed back at her.

I think the larger issues of abuse in the comics industry are genuine and I share everyone's concerns. As a father to a young daughter showing an interest in making her own comics, I do really care about this stuff. So I don’t want our difference of accounts to take attention away from that industry-wide discussion that needs to happen.
