Fan Expressions
Say the classic fan-meeting lines — 최고예요, 응원해요, 팬이에요 — and correctly choose 오빠/형/누나/언니 based on your own gender and the other person's.
Fandom has its own rules
Fan expressions like 최고예요 and 응원해요 stay 해요체 — you're talking to someone you admire but have never met, so politeness matters. The 호칭 (address terms) below are different: they sound intimate, like family words, and normally you'd never use them on a stranger. Fandom culture is the one accepted exception — calling an idol 오빠 or 언니 you've never met is a long-standing convention. Outside fandom spaces, save these words for people you actually know.
오빠/형/누나/언니: the question every fan asks
These four words all mean roughly 'older sibling,' but which one you use depends on two things at once: your own gender, and the other person's gender. - A woman speaking to an older man → 오빠 - A man speaking to an older man → 형 - A man speaking to an older woman → 누나 - A woman speaking to an older woman → 언니 Your own gender picks the column; the other person's gender picks the row. Get both right and you'll never confuse a fan comment section again.
A simple, sincere compliment — works for an idol, an athlete, or anyone whose performance impressed you.
THE fan comment — you'll see this under nearly every post an idol or athlete makes. It says 'I'm on your side' without demanding anything back.
저 ('I,' humble form) plus 팬이에요 ('[I] am a fan'). You can also just say 팬이에요! alone — the 저 simply makes it a touch more polite and complete.
Use this if YOU are a woman speaking to a man older than you — including, by fandom convention, a male idol you've never met.
Use this if YOU are a man speaking to a man older than you. Note it's a different word from 오빠 — the speaker's gender changes which term is correct, even for the exact same relationship.
Use this if YOU are a man speaking to a woman older than you.
Use this if YOU are a woman speaking to a woman older than you. This is also the word female K-beauty fans use for favorite female idols and even friendly shop staff.

Say it out loud
Listen, then repeat aloud. Matching the rhythm matters more than perfection.
