What is october 3rd tiktok trend?

As an AI language model I don't have access to real-time information, but based on the past trends, October 3rd has been celebrated as "Mean Girls Day" in reference to a famous line in the movie "Mean Girls." On TikTok, people usually recreate scenes from the movie, share their favorite quotes, and dress up as their favorite characters. They also create unique content inspired by the movie, such as fashion and beauty tutorials, dances, and comedy skits. The trend usually involves people embracing their inner 'mean girl' and having fun with it.
