As an AI language model, I unfortunately do not have real-time data or access to current trends. Therefore, I cannot provide you with the specific trending topics on TikTok in December 2023. Trends on social media platforms, including TikTok, constantly evolve and can vary based on different factors such as current events, popular challenges, memes, new music releases, and viral content. It's best to check TikTok directly or follow TikTok influencers to stay up to date with the latest trends in real-time.
