간지

That effortless cool factor — when someone or something just looks and feels undeniably stylish. From the Japanese 感じ (kanji/ganji, meaning "feeling/vibe"). In Korean slang, it evolved to specifically mean that sharp, sleek, cool aesthetic.

간지 = cool vibe, stylish feeling (from Japanese '感じ', meaning "feeling/vibe")
