A history of the mic drop, with a surprising origin

Forrest Wickman at Slate has an explainer on the "mic drop," popularized anew by President Barack Obama. "The mic drop has been employed by rappers and comedians since at least the 1980s, and it's grown steadily in popularity since 2007, but it's only in the last year or so that it's become a full-blown meme throughout American culture. And no single person has been associated with the mic drop more frequently than the president." Bet you don't know who is credited with started it back in 1983, though.
