The hottest TikTok trends right now: December 2025
Dive into the latest TikTok trends right now: embarrassing catchphrases, Stranger Things, and more are all covered by Epidemic Sound’s social media expert.
Another month, another absolutely wild time online. Join Epidemic Sound’s community manager, Madie Hooker, as she breaks down five of the latest TikTok trends.
Trend 1: Come on, Superman…say your stupid line
One of TikTok’s unique selling points is that an old song is reborn pretty much every day. This month, Tame Impala’s The Less I Know the Better, first released in 2015, has been revived thanks to its meme-able lyric: “Come on, Superman…say your stupid line.”
It’s a bitter, downtrodden breakup jam for everyone who’s experienced unrequited love. Well, maybe not for TikTok users. Instead, they’ve had a little fun with it.
“Say your stupid line” is no longer an insult — it’s a literal call to admit your own stupid line. Something you do way too much, that you can’t help but say. The next time you see someone lip-sync to Tame Impala with the caption “The year’s just gone by sooo fast,” you’ll know why.

Trend 2: Stranger Things fan theories
For nearly a decade, Stranger Things has given viewers enough thrills, iconic needle drops, and Stephen King worship to last a lifetime. As the series draws to a close on New Year’s Eve, fan theories are spreading like wildfire.
We won’t say what we think or spoil the fun. But if you want to get in on the action, grab a Stranger Things-style synthwave track and let your imagination run a marathon.
Trend 3: Sean Combs: The Reckoning
Netflix’s commitment to zeitgeist-catching is almost unmatched — there was a time when everyone you knew sat down to watch Tiger King. Following in those true-crime footsteps, Sean Combs: The Reckoning unpicked Sean “Diddy” Combs’ years of alleged misconduct.
It’s an uncomfortable portrait of a man accused of serious crimes, but TikTok also saw a different angle. The series was executive-produced by Combs’ longtime rival, 50 Cent, whom social media has called “a menace” and “hater of the century.”
This comes from 50 Cent’s decision to promote the project through an interview with ABC News, which some users believe Combs can access in prison. Considering 50 Cent’s often controversial social media use in the past, it’s easy to see why some might think that.

Trend 4: Zara Larsson’s Lush Life dance
Zara Larsson is already a pop icon, but as her Midnight Sun tour rolled across Europe, TikTok embraced one of the Swedish singer’s older hits. While performing 2017’s Lush Life, Larsson invited a 16-year-old fan on stage to dance along.
The fan crushed the choreography, turning it into an at-home TikTok trend as well as an unmissable live staple.
