Break Your Legs💢 #ITZY #YEJI #LIA #예지 #리아

What happened

ITZY's channel posted a video titled "break your legs" and tagged with members Yeji and Lia. Its auto-generated captions are almost entirely the phrases "break your legs", "break them" and "break them now", repeated.

In the Korean comments

One comment leans on a specific word, 개다리춤 (gaedarichum, a goofy, loose-legged dance), and a specific label, 언니라인 (eonni line, a group's older members). In translation it reads: "lol, the older line looks pretty even doing the goofy leg dance." The video is tagged with Yeji and Lia, but the comment itself names no one. A second comment says this looks like old choreography and that the two of them did a lot of moves like it. That is the commenter's recollection; the title and captions do not confirm it. A third calls the video a trend and singles out one member. In translation: "This trend suits Lia well, lol." The word trend comes from the commenter, not from the title or captions.

What the words mean

개다리춤 (gaedarichum) reads literally as "dog-leg dance". In everyday Korean it names a comically loose, wobbly dance done with the legs, and people usually say it jokingly. So when the comment says the older line looks pretty even doing it, the tone is affectionate praise: a dance with a goofy name still looks good on them. The register is casual and teasing, and the comment opens with typed laughter. Nothing in the title or captions describes the dance itself, so the word is the commenter's label for it.
