Wielding a root veggie, Michelle Obama answers: "Turn Down For What?"

The average public official probably wouldn't lend credence to a social media post trolling them about an activity that Urban Dictionary defines as "being wild" and "acting crazy" in sexual or drug-induced endeavors.

But apparently, Michelle Obama is no average public official.

On Tuesday, Iman Crosson - a YouTube-famous impressionist best known for his impersonation of President Obama - contributed a question to the "Let's Move!" Q&A the first lady is hosting on Vine to promote healthy eating and an active lifestyle.

Putting on his best "Barack" face, Crosson says in the six-second video, "A question for the first lady: How many calories do you burn every time you 'turn up'?" The phrase is used in modern slang to describe extreme partying.

Wielding a turnip, Michelle Obama responded in a Vine of her own remixing Lil John's "Turn Down For What?" in which she dances with the root vegetable inquiring, "Turnip for what?" Last week, Lil Jon via Rock the Vote released a version of the popular rap song called "Turn Out For What," encouraging young people to vote in next month's midterms.
