Aegyo 애교

A deliberately cute manner — baby-voiced talk, puffed cheeks, finger hearts, whiny charm — performed to be adorable and win someone over. It can be a personality trait ("she's full of aegyo") or an on-demand performance. Both men and women do it; male idols' aegyo is a fandom delight of its own.

Aegyo-sal 애교살

The small pouch of fat directly under the eyes that plumps up when you smile, making the eyes look bigger, younger, and friendlier. In K-beauty it's a coveted feature — the opposite of Western makeup's war on under-eye anything. People highlight it with makeup or even get fillers to create it.

Skinship 스킨십

Affectionate physical touch — holding hands, back-hugs, leaning on shoulders, playing with someone's hair. It covers romantic touch between couples, but also the casual same-sex physical closeness that's normal between Korean friends and idol group members. It's a Konglish word, so don't expect English speakers outside K-culture circles to know it.

Kkondae 꼰대

A condescending older person — typically a boss or senior — who lectures juniors, demands deference because of age or rank, and starts sentences with "back in my day." Think "OK boomer" energy fused with a know-it-all manager. Younger Koreans use it behind such a person's back, never to their face.

Nunchi 눈치

The subtle art of reading a room: sensing other people's unspoken moods, needs, and the social hierarchy, then adjusting your behavior before anyone has to say a word. Someone with quick nunchi (nunchi-ga ppareuda) notices the boss is irritated or a friend is hurting without being told; someone with no nunchi (nunchi-ga eopda) blunders straight through social cues. In Korea's high-context, hierarchy-aware culture it's treated as a core life skill — for getting along at work, in family, and among friends.

Jeong 정

A deep, slow-growing bond of attachment that forms between people — and even toward places, pets, or objects — through shared time and experience. It's broader than love or friendship: Koreans speak of miun jeong (미운 정), the attachment you develop even toward someone who drives you crazy, alongside goun jeong (고운 정), fond attachment. Jeong is described as something that 'seeps in' (jeong-i deulda) rather than something you choose, and it's often cited as a defining trait of Korean relationships.
