The #MannequinChallenge is a new 2016 trend or internet "meme" that everyone is doing.
This new trend is very popular among celebrities and college and professional athletes, but it is especially popular among teenagers. The point of the challenge is for a group of people to freeze as if they were mannequins. One person with a camera then moves through the group, showing different angles. Participants can also change thier position while the camera isn't facing the group.
A segment from the song "Black Beatles" by Rae Sremmurd is often played in the background as the group remains still, but other songs can be used. According to CNN, the first posting of the challenge happened last month at a high school in Jacksonville, Florida.
Although this challenge is popular now, it isn't the only challenge that has been around for some time.
Many other challenges like the Fight the Air Challenge, the Harlem Shake, and the Planking Challenge are just some other Challenges that were once popular among teenagers.
