Urban Dictionary, the Oxford of internet lingo, defines "mic drop" as: "When a performer or speaker intentionally drops/throws the microphone on the floor after an awesome performance."
A photo of First Lady Michelle Obama, on stage at the Democratic Convention, wearing a royal blue Christian Siriano dress should be used to illustrate the mic drop. A sartorial mic drop.

Michelle Obama's emotional speech
'I wake up every morning in a house built by slaves' says Michelle Obama in an emotional speech to the Democratic Convention.
While these conventions are not about the clothes, they have offered up many fashion moments.
The most powerful so far was the outgoing First Lady. Obama's simple cap sleeve cobalt frock matched the blue backdrop, and allowed her appearance to take a back seat while she eviscerated Hillary Clinton's opponent without even mentioning his name. However, it is just the second time she has donned a gown by Siriano, a Project Runway winner who has made a career out of designing for women of all shapes, sizes and ages.

He most recently made headlines for offering to dress Ghostbusters star, 1.8-metre tall Leslie Jones when other designers refused to. This is following his plus-size collection for retailer Lane Bryant, which he showed at a runway show at the United Nations in New York this year.
Since Jackie O the outfit choices of the prominent ladies of American politics have captivated fashion watchers, commentators and retailers. Now, just like the speeches made by the wearers, the dresses of the Republican and Democrat conventions have been analysed and unpacked until they are threadbare.
Last week Melania Trump, wife of Republican presidential nominee and FLOTUS wannabe, broke with tradition of First Lady-in-waiting etiquette, and then the internet itself, when she took to the stage to endorse her husband in an ivory dress by Roksanda.
"Unlike pretty much every would-be first lady, Ms Trump wore a dress not by an American label, but by Roksanda Ilincic, a Serbian-born designer based in London," New York Times fashion editor Vanessa Friedman opined.

It appears outfit outranked speech on her Cleveland to-do list, as the dress – derivative of Seinfeld's puffy shirt – featured more strategy in its billowy sleeves than her entire, possibly plagiarised address.
"Ms Ilincic's story parallels Ms Trump's nicely: She was born in Serbia, which, like Ms Trump's native Slovenia, was part of Yugoslavia at the time; and like Ms Trump, she found her way out via a career in fashion. It shadows Ms Trump's own American fairytale."

Trump bought the dress herself, according to a spokesman, which sold for close to $3000 online via Net-A-Porter. It then quickly sold out, quite the coup for the British-born fashion e-tailer that was sold to Swiss-owned luxury retailer Richemont in 2010.
Ivanka Trump was next up on the RNC catwalk and turned heads when she took to the lectern in a blush column gown from her eponymous line. The sheath dress sold out via her online stockists including American department stores Macy's and Nordstrom.
It had all the makings for a pitch perfect on-brand message for the man who said he'll bring manufacturing jobs back to the United States, until you read the small print. In between learning it was made from a combination of polyester/spandex, Trump's dress, like most of her fashion line, was "imported".
A foreign-made dress during a prime time address could be the least of Ms Trump's worries as she prepares to deal with a lawsuit lodged by Italian footwear company Aquazzura, which claims she stole designs for her footwear collection. The styles of which are also "imported" according to stockist Lord & Taylor.
