Oxford Dictionary Word of the Year: "Post-Truth"

In vicinities where moral relativism holds sway, "post-truth" refers to the fact that the ideology-driven narrative, not the truth, is what matters. (In places where such relativism is shunned, "post-truth" is known more simply as "a lie.")

Barack Obama, the man who lied his way through his presidency which such deathless lines as "If you like your doctor, you can keep your doctor"? He's a "post-truth" POTUS.
