It’s easy to lose track of time and fall into mindless scrolling while on TikTok. The platform stores countless videos that cover a massive range of topics—even ones you’re not looking for (that’s arguably the best part of the app). Launched in China in 2016, TikTok currently has over 100 million active monthly users in the US alone, and has been downloaded over 2 billion times worldwide.

Somehow, the app knows which videos to place in front of users and the perfect time to push those videos forward. That insane algorithm has created one of the best spaces to start viral trends. But it’s not just the algorithms that make TikTok pop. The music, editing tools, filters, and variety of video effects also help users create short clips, up to 60 seconds long, that are entertaining and shareable. It’s even beginning to adopt the features of some other popular social media apps to make it a true one-stop shop. Despite some Black creators being left uncredited or having their work stolen for a viral trend, or trends having deadly outcomes, the app still aims to be an outlet for creators to make a new style of social media content.

We’ve all seen viral dances, pranks, skits, stories, and challenges make their way from TikTok to other media platforms; sometimes it’s hard to keep up with what’s what. But Complex has you covered. Here are some of the best TikTok trends and challenges to watch right now.
