Unless you’ve been living under a rock, you’ll know that ATEEZ (에이티즈), more specifically San (산), has been garnering attention with their “BAD” dance challenge. Well, they recently made more waves with the challenge, thanks to TWICE’s (트와이스) main dancer Momo (모모).
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 danced to the song’s viral dance break, which has taken social media by storm. The dance break centres on San and has been gaining momentum online, specifically for the chest-popping move.

In the video, the two dancers showed off their impeccable skills, hitting every move with ease. It’s also worth noting that the two were dressed casually, with San wearing a fitted black t-shirt and Momo wearing a black tank top. However, the outfit choice accentuated their physique, making their sharp dance moves more apparent.
Within 12 hours, the video has amassed over 3 million views on TikTok and 8 million on Instagram, highlighting the public’s interest in San and Momo’s collaboration. The comment sections were filled with ATINYs (ATEEZ fans) and ONCEs (TWICE fans) reacting to the video, unsurprisingly ecstatic over the collaboration.
Many quipped that they were hooked right from the beginning, when San’s broad shoulders easily covered Momo’s entire frame. Along with praises for their complementary dance moves, fans and netizens also praised the two stars’ visuals, with some joking that the entire video is a feast for the eyes.
Since ATEEZ’s comeback in late June, many have taken part in the dance challenge. One of San’s fancams from the comeback has also gained over 2 million views, highlighting a broader interest in the choreography. However, despite many other male idols trying to replicate San’s viral dance break, many fans quipped that no one has been able to outdo the original.
Of course, San and Momo’s collaboration will only add to the virality of “BAD”, bringing more attention to the song and the choreography. What are your thoughts on the two idols’ take on the dance challenge? In the meantime, check out the “BAD” music video and San’s viral fancam below:
