Over recent years we have seen internet crazes take off and become the thing that you just have to do. From the Harlem Shake to Ice Bucket Challenges, each year there is something new. And this year is like no other. Introducing the Mannequin Challenge.
If this is the first you're hearing about the internet phenomenon, then where have you been! Even some of our favourite celebs, sport stars and personalities have got on board, from the likes of music superstars Destiny's Child and Adele to even making it's way to the White House, where the basketball team Cleveland Cavaliers called up First Lady, Michelle Obama to help pull off their challenge. Presidential candidate Hillary Clinton even took part in her own attempt in one last bid to gain those Millennial votes.
But what exactly is it? Well, it's basically exactly what it says on the tin. All you have to do is pose and keep that pose - like a mannequin - whilst someone goes round and films everyone. Once the clip is all done and dusted, users share the footage with the hashtag #MannequinChallenge. The crazier the pose the better.
