San & Momo Set the Internet on Fire with “BAD” Dance Challenge Collab

If you’ve been online lately, you already know ATEEZ’s San has been turning heads with his “BAD” dance challenge. Now TWICE’s main dancer Momo has joined him, and the internet can’t stop watching.

On 27th July 2026 (Monday), ATEEZ’s official social media pages unveiled San and Momo’s collaboration for the “BAD” challenge. In the video, the two idols performed the song’s viral dance break, a routine centered on San that has been gaining massive attention online — especially for the chest-popping move. Both stars danced in relaxed but fitted outfits: San wore a black t-shirt, Momo wore a black tank top. The styling made their sharp movement and control even more striking.

The response was immediate. Within 12 hours, the video had amassed over 3 million views on TikTok and 8 million on Instagram. Comment sections filled up quickly with ATINYs and ONCEs, both fandoms reacting with predictable excitement. Many users pointed to the opening moment, where San’s broad shoulders easily covered Momo’s entire frame, as the exact point they were hooked. Others praised the two idols for complementary dance styles and visuals, with some joking that the entire video is a feast for the eyes.

This isn’t happening in isolation. Since ATEEZ’s comeback in late June, the “BAD” challenge has pulled in plenty of participants. One of San’s fancams from the comeback has already passed 2 million views, showing just how much traction the choreography has gained. And though several other male idols have tried to match San’s viral dance break, fans have been quick to say that no one has managed to outdo the original.

San and Momo’s collaboration only adds more momentum to “BAD”, bringing fresh attention to the song and its choreography. If you want to feel that same sharpness and confidence in your own movements, GoDance has classes that break down viral choreography step by step.
