When a performer or speaker intentionally drops/throws the microphone on the floor after an awesome performance.
President Obama this past weekend addressed the Congressional Black Caucus and told them to stop complaining, stop grumbling, stop crying, and help him fix the economy and get reelected. Though, I'm not sure if the mic drop was necessary.
