I don’t like the word “mansplaining.” I don’t think it’s a clever enough blend to have caught on the way it has, unless I’m misunderstanding. But I also can’t come up with anything better.
“Dicksplaining” at least gets the sound right, and mansplainers ARE often dicks, but it’s probably too late to win this battle.
Anyway. This is still a solid joke I saw on Twitter.
