Inspiring Octogenarians 'Whip,' Now Watch Them 'Nae Nae'

These two grandmas have got some serious stanky leg style .

Mary Thompson, 80, and Eleanor Fredriksen, 83, bust inspiring moves to rapper Silento's "Watch Me (Whip/Nae Nae)" in video sweeping the Internet.

The best friends whip, nae nae and even Superman in a hallway at the Somerby of Peachtree City Retirement Community  in Georgia.

Footage filmed by Somerby's lifestyle director, Jessica Holt, was posted to Facebook on Monday and has been seen more than 15 million times as of Friday morning.

"We make it a priority to surprise and delight our residents, but this week, the tables were turned," the community's COO, Amy McKinley, told The Atlanta Journal-Constitution.

Dancing "just feels like a natural thing when I hear the music," Thompson told Fox 5 News. "I just like to be happy and I was having a good time with my friend Mary," added Fredriksen.  

The duo became firm friends in 2014 after Thompson moved into the facility.
