Flash mobs are organized gatherings of people in a public place, who perform a rehearsed action and then disperse, often for the purpose of entertainment or social commentary. Flash mobs have become increasingly popular in recent years, thanks in part to the rise of social media. YouTube is a popular platform for sharing flash mob videos, and there are many channels dedicated to showcasing the best flash mobs from around the world.
Some of the most popular flash mobs on YouTube include dance routines, choreographed performances, and even marriage proposals. Flash mobs can be a lot of fun to watch, and they can also be a great way to bring people together. They can also be used to raise awareness for important social issues.
