The FIRST question Koreans ask new people is 몇 년생? (what birth year?). It's not rude — it's social navigation. Your birth year determines EVERYTHING: who speaks formally, who pours drinks, who pays.
Age hierarchy rules
1살이라도 많으면 = 선배 대우Even 1 year older = treated as senior
빠른 년생 = 같은 학년이지만 나이가 많음'Fast' year = same school year but older birthday
동갑 = 같은 나이 → 반말 가능Same age → casual speech allowed
나이 들으면 반말 → 존댓말로 바꾸기Finding out someone is older → switch to polite speech
외국인 예외?Foreigner exception? (sometimes, but not always)
빠른 ○○년생 (fast year) is uniquely Korean: if you were born Jan-Feb 1995 but entered school with 1994 kids, you're 'fast 95.' This creates endless confusion about who is 'really' older. Koreans debate this seriously.
Age-related phrases
The most liberating Korean phrase: 말 놓으세요 / 반말 해도 돼요 (you can speak casually). When someone older says this to you, the relationship just leveled up. But YOU can't decide to speak casually to someone older — THEY grant it. Power flows downward in Korean age hierarchy.
