What does 참코 애발매일 mean?

Question

So I’m trying to join a silent chat room and it requires a passcode. The passcode hint is ‘참코 애발매일 YYMMDD’. What does it mean?

Answer 1

Had no clue at first sight. Searched up a bit to figure it out.

“참코: 애 발매일.”

• 참코: 참가_{參加 joining} 코드_code; passcode required to join.
• 애: the name of the Stray Kids’ digital single “Mixtape:애.”
• 발매일: 발매_{發賣 release}-일_{日 date}; release date.

“Passcode hint — the release date of the Stray Kids’ digital single ‘Mixtape:애.’”

Which is June 26, 2021. It’s 210626. There you go. Good luck with your K-pop journey.

Answer 2

1. 참코 애 -> no clue.
2. 발매일 YYMMDD -> release date YYMMDD

First part of the phrase means nothing. Some jargon maybe. You would have to figure out by yourself.
