>>94327892As far as I can tell it's when a man condescendingly explains something a woman already knows to her because as a woman he thinks of her as less intelligent.
It's also completely impossible to determine whether someone is "mansplaining" or is just a condescending asshole and gender has nothing to do with it.
But hey, at least it's not as retarded as "manspreading," where women confused men spreading their legs to prevent crushing their bait and tackle for some kind of sexual dominance posturing.
tl;dr an oversimplification of a common social problem everyone faces made feminist
