What’s trending on TikTok in December 2025?

From Christmas nostalgia to deepfake chaos, December 2025 gave TikTok one of its wildest feeds yet.

December on TikTok is a blur of fairy lights, family moments and conspiracy-level AI glitches. The vibe? Somewhere between a holiday card and a deepfake rabbit hole.

It’s festive, chaotic, deeply personal, and just a little unhinged.

Christmas core: Nostalgia in 15 Seconds

TikTok has officially gone full Christmas. The feed is packed with cozy lights, snowy edits, slowed-down Christmas classics, and “what my childhood Decembers looked like” reels.

The Rise of family tok

This December, families are the new creators. Not just “parents featuring in a video”,but entire family units turning their daily lives into serialized content.

Fake AI, real reactions

TikTok’s obsession with AI has entered its weirdest phase yet. Creators are posting eerily realistic AI-generated videos, from fake news clips to deepfake characters caught “on camera.”
