I'm going to preserve this in shorts😝

In the Korean comments

One top comment reads, in translation, “Eunchae twisting her pigtails while she talks—such a little kid.” The original calls her a 잼민이 (jaemini, childish kid), playful slang that makes her exaggeratedly childlike behavior the joke. Another commenter says they initially mistook the clip for a fan-made video, only to find Eunchae’s moment preserved on the official channel.

What the words mean

박제할거임 (bakjehal geoim) literally means “I’m going to preserve or stuff it,” as in taxidermy. Online, 박제하다 (bakjehada, to immortalize online) means posting and permanently preserving a memorable or embarrassing moment. The title is casual, exaggerated teasing: “I’m putting this in a Short so it lives forever.”
