Young Thug may have just posted the most stuntastic #MannequinChallenge yet. Thugger and company are boarding a private jet with new music playing. What started off in high school hallways and ended up on NFL football fields has now made its way to private jets. The viral sensation known as the #mannequinchallenge just entered another tax bracket with Young Thug leading the charge. Thugger can be seen boarding a jet with his crew including producer TM88 of 808 Mafia as a new song from he and 21 Savage play in the background. Plenty of flenching and eye blinking can be seen, but it still came out cool. Music by: @thuggerthugger1…
