2 Chainz, the marketing genius that he is, has banked off the hottest new viral movement, the #MannequinChallenge, with his "Countin" video, in which he enters a boutique where he's the only one who isn't completely motionless. Those who he selectively unfreezes immediately join him in turning up. People all over social media have been creating their own videos of themselves posing as dummies, and the latest rapper to try out the viral stunt is Young Thug. During the Mannequin Challenge video he posted to his Instagram, an unreleased track from him and 21 Savage plays in the background. The snippet, during which one can only hear 21, sounds hard as hell. One can hear the tag of Thugger's right-hand man Wheezy at the beginning of the clip. 

Thugger's Mannequin Challenge takes place in and outside of a private jet, and he even got a couple of runway staff members to participate. One can spot TM88, who froze himself as he was on his way up the stairs to the plane, with a box of Fruit Roll-Ups in his right hand. The cameraman boards the plane and then ventures into the cabin to find Jeffery, who is stuck in a dignified thinking man's pose. He springs to life and flashes his brilliant veneer right before the clip ends.  

Thug and 21 recently appeared together on Meek Mill's DC4 track "Offended." Strangely enough, a sans-Meek Mill version of the song, entitled "I Might," is now listed on iTunes as a Young Thug single. Less surprisingly, Meek Mill was left out of the song when it played on OVO Sound Radio this weekend. 

Thoughts on the Thug/21 collab -- potentially titled "Turn Up" or "Turn Up on Dey Ass" -- heard in the above video?
