2. "Alt" TikTok

While TikTok gained notoriety for its viral dance trends, it was only a matter of time before the platform algorithmically divided its users into different "sides" of the app. Users began calling themselves "alt" or "deep" TikTok users, versus "straight" TikTok users. Rather than seeing content about mainstream trends, "Alt Tiktok" users found themselves seeing more surreal content. Much like the "hipster" and "fandom" factions of Tumblr, "Alt TikTok" users found some sense of pride in not being part of the mainstream culture.

6. Learning that one very confusing dance move

Some refer to it as twerking, and others describe it as throwing it back. Many TikTok users call it the "booty shake" because there really is no better way to describe it. No matter what you call it, the move has eluded TikTok users who just can't seem to move their body that way, and sparked an even larger trend of trying to learn how to do it. Don't worry — there are plenty of tutorials online.

2021 is sure to bring even more bizarre TikTok content.
