1. What does it mean?
답멘 combines 답, a reply, with a shortened 멘션. It often refers to replying publicly to someone who addressed you on Twitter/X, rather than sending a private direct message.
Also written or said as dammen
2. The nuance
The exact interface depends on the platform. 답멘이 늦다 says the reply is late; it does not automatically mean the person deliberately ignored you.
3. Examples
“전시 준비하느라 답멘이 늦었어.”
I replied late because I was preparing for the exhibition.
“추천해 준 분께 답멘으로 감사 인사를 남겼어.”
I thanked the person who recommended it in a reply.
