If you follow K-pop, 막내 (maknae) is everywhere — the youngest member, fussed over by the group and often the 'cute' one. It started as a plain family word for the youngest child and became fandom vocabulary. Here's what it really means, the 'maknae line' and 'golden maknae' fans talk about, and how it fits alongside the older-sibling terms. It's part of the same age-and-respect system behind Korean honorifics.
The meaning: the youngest one
막내 is a noun meaning 'the youngest' in a defined group — a family, a team, a company department, a circle of friends. Being the 막내 is a recognized role: the youngest is usually looked after by everyone older, and in return is expected to be respectful and helpful. It's warm, not belittling.
- 막내maknae

A noun/role, not a term you call someone to their face like 오빠.
- 제가 막내예요jega maknaeyeyo

How you'd introduce your place in a family or team.
- 막내가 제일 귀여워maknaega jeil gwiyeowo
The maknae is the cutest.
The classic 'baby of the group' affection.
Maknae line and golden maknae
In fandom, a group splits into the 'hyung/unnie line' (older members) and the 'maknae line' (youngest members). The single youngest is THE 막내. A 막내 who's freakishly talented across the board earns the title 황금막내 ('golden maknae') — a tag BTS's Jungkook made famous and fans now hand to standout youngest members in other groups.
- 막내 라인maknae line

Fan shorthand. Opposite of 형 라인 (hyung line).
- 황금막내hwanggeum maknae
golden maknae — talented at everything
황금 = 'golden'. A praise nickname for a gifted youngest member.
- 동생dongsaeng
younger sibling / younger person (general)
Any younger person — 막내 is specifically the very youngest.
How it fits with the older-sibling terms
막내 sits at the bottom of the same age ladder as the older-sibling words. Where you call someone older 오빠, 언니, 형, or 누나, the youngest of the whole group is the 막내.
