Combination of Man and Explaining.
When a man explains to a woman in full detail something that is very easy to understand of that the woman knows about. It commonly is heard whenever a feminist is around and she doesn't like the way shes being talked to.

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.

Mansplaining is the act of a man explaining something he may not really know to a woman who does, and the assumption behind it that knowledge is somehow inherent in the male condition, paralleling a void of knowledge waiting to be filled in the female condition.
He didn't realize it, but he was mansplaining how a woman's reproductive system works to a gynecologist (who just happened to be female).
