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.
Factual Person: No, they don't. that statistic is just for overall median pay of full time workers, and does not account for overtime hours worked, location, experience, degree earned, or even the field someone is working in. Women make less on average because men and women make different career choices, because believe it or not, men and women are different.
Feminist: Don't you mansplain to me! Facts and logic are just oppressive constructs to keep women down!
Man: "Actually, the study which suggested an autism link was a hoax, and the scientist who submitted it was disbarred."
Woman: "Check your privilege, you're mansplaining.
...Therefore its all womens fault."
Explainer: That is a misleading statement. In fact, after correcting for factors like hours worked, experience, physical danger involved, etc., the differences is just a few percent.
Explainee (sarcastic): Thank you for mansplaining! I would never have thought of that with my tiny little brain!
Mansplain--to put women down in response to criticism.
