If you are new to K-pop, “Who’s your bias?” is one of the first questions you hear. Then Korean posts introduce a second vocabulary: 최애, 입덕, 덕질, 탈덕. Same feelings, different words.

Quick answer: your bias is your favorite member. Korean fans usually say 최애 (choe-ae) for the same idea. But many fandom words don’t translate one-to-one — some were replaced, and some travelled the world in Korean.

So the useful question isn’t “What’s the literal translation?” It’s “What would fans in my language actually say in the same situation?” Tap 🔊 to hear each Korean word.

These are the closest real-world equivalents, not perfect dictionary matches — fandom words shift with context.

1. 최애 — choe-ae

Closest English: bias. 최애 means the person you like most — in idol fandom, your favorite member. English-speaking fans say bias.

It’s a shortcut, not a perfect match: Koreans also use 최애 for a favorite actor, character or even food, while bias is fandom-specific.

2. 입덕 — ipdeok

Closest English: get into / start stanning. 입덕 is the moment or process of becoming a fan. One fancam becomes five, you learn the members, and suddenly it’s 2 a.m. and you’re watching old variety clips.

The 덕 in these words comes from 덕후, the Korean take on the Japanese word otaku. 입 means “enter” — so 입덕 is literally “entering fandom.”

3. 덕질 — deokjil

Closest English: stanning / fan activities. 덕질 is everything you actually do as a fan: streaming, collecting photocards, voting, going to concerts, following updates and talking with other fans.

Stanning overlaps, but 덕질 names the whole bundle of fan activity rather than one action.

4. 탈덕 — taldeok

Closest English: unstan / leave the fandom. 탈덕 is the opposite of 입덕 — leaving a fandom or ending active fan life. 탈 means “exit.”

Put together, 입덕 → 덕질 → 탈덕 makes fandom sound like entering, living in and eventually leaving a small world.

5. 막내 — maknae

Closest English: maknae. 막내 is an ordinary Korean word for the youngest in a family or group. International fans kept the Korean word itself.

It’s the opposite of what happened to 최애: English fandom chose bias over choe-ae, but maknae crossed the language barrier intact.

6. 컴백 — keombaek

Closest English: comeback. 컴백 came from English, but K-pop reshaped it. In everyday English a comeback follows a long absence; in K-pop, a group can have a comeback a few months after its last release. What “comeback” really means in K-pop.

7. 사생 — sasaeng

Closest English: sasaeng. 사생 is short for 사생팬, from 사생활 (private life): a fan who seriously invades an idol’s privacy. International fandom kept the Korean word, because no English word quite covers it.

8. 공방 — gongbang

Closest English: music-show recording / pre-recording. 공방 is short for 공개방송 (public broadcast) — the music-show recordings fans can attend. Don’t confuse it with the everyday word 공방 (workshop).

9. 차애 — cha-ae

Closest English: second bias (close to bias wrecker). 차애 is your second favorite member — the one right after your 최애. A bias wrecker is the member who threatens to take your bias’s place; 차애 is calmer, but both describe that “second heart.”

Korean fans may joke “최애 바뀌겠다” (my 최애 might change) when a 차애 gets too strong.

10. 본진 — bonjin

Closest English: ult group / main fandom. 본진 (literally “headquarters”) is your main fandom — the group you support above all others. It’s close to an ult group.

Fans who love many groups at once are called 잡덕 (jap-deok), roughly a multi-stan.

Why do some Korean words travel while others get replaced?

Fandom language isn’t built by dictionaries; it’s built by repetition. If a local fandom already has a short, useful word — like bias — that word wins. If the Korean word names something culture-specific — like maknae or sasaeng — the Korean form travels with K-pop itself.

Comeback took the strangest route: an English word entered Korean pop culture, picked up a K-pop meaning, and returned to global fandom with that new meaning attached.

Fans also borrow everyday Korean words: many call older male idols “oppa” — here’s what oppa really means.
