K-pop Terms Every New Fan Should Know: The Glossary

K-pop has a vocabulary, and nobody hands you the dictionary. You learn it by being confused in comment sections until it clicks.

Using the vocabulary

You do not need all of it at once. The five that matter on day one are bias, comeback, maknae, photocard and fanchant; with those you can follow most conversations. The rest arrives on its own, one confused comment section at a time.

And when you are ready to use it on someone, the K-pop terms that open the most conversations are the simplest: "who is your bias" and "what is your ult group". On K-pop Dating, both answers sit on the front of every profile, which is why the first message between two fans is never the hard part.
