1. What does it mean?
박제 borrows the image of preserving a specimen. Online it means fixing a post, comment, or moment in a lasting record, often so it remains visible after the original changes or disappears.
Also written or said as bakje
2. The nuance
It can preserve a funny compliment, but can also become public shaming. A screenshot may omit context or expose personal information; the term itself does not justify distributing it.
3. Examples
“친구가 허락해서 웃긴 오타를 우리 채팅방에 박제했어.”
My friend agreed, so we saved the funny typo in our chat.
“장난으로 박제한다 해도 남의 연락처는 올리면 안 되지.”
Even a joking screenshot archive shouldn't expose someone else's contact details.
