As debate about the definition of the word literally changing to mean figuratively rages on, it turns out that—as with many other things—John Oliver already has it figured it out.
On one of his shows, he signified that he was speaking literally, not figuratively, by saying, "...It was literally, literally true." I've found that approach has slipped into my own vocabulary to a point of near-overuse.
So that's the new word for literally: literally-literally.
Please make a note of it.
Sidebar: I've written and looked at the word literally so much in the last few minutes, it has ceased to have meaning in the way a word sometimes does when you stare at it too long.
