The White Helmets, officially known as Syria Civil Defence, is a volunteer organisation that operates in parts of opposition-controlled Syria and in Turkey. Formed in 2014 during the Syrian Civil War, the majority of the volunteers' activity in Syria consists of medical evacuation, urban search and rescue in response to bombing, evacuation of civilians from danger areas, and essential service delivery. As of April 2018, the organisation said it had saved about 114,000 lives, and that 204 of its members had lost their lives while performing their duties. They assert their impartiality in the Syrian conflict.

The Mannequin Challenge is a viral Internet video trend which became popular in November 2016. In this challenge, participants have to stay still in action like a mannequin while a moving camera films them, often with the song "Black Beatles" by Rae Sremmurd playing in the background. The hashtag #MannequinChallenge was used for popular social media platforms such as Twitter and Instagram. It is believed that the phenomenon was started by students at a high school in Jacksonville, Florida. The initial posting has inspired works by other groups, especially professional athletes and sports teams, who have posted increasingly complex and elaborate videos.
