What does “맹랑하다 (maengnanghada)” mean in Korean?

맹랑하다 (maengnanghada) describes someone unexpectedly sharp and bold — cheeky, pert, sometimes downright impertinent. Depending on tone it can be affectionate (an adorably saucy kid who outwits you) or pointed (someone brazen beyond their years or station). The dictionary captures the cute side as 똘똘하고 깜찍하게 (smart and adorably saucy), but the common thread is being sharper or more forward than expected — a personality, not a comment on manners.

The makeup ad plays it for charm: a lip-tint shade nicknamed 맹랑한 체리 (“cheeky-clever cherry”) is set against a 무심한 (musimhan, “nonchalant / unbothered”) look — 맹랑 찰스 vs 무심 찰스, two opposite moods in one face. So you learn a pair at once: 맹랑한 = pert and playful, 무심한 = cool and indifferent. Note the spoken “맥랑” you may hear is just a casual slur of 맹랑 — the dictionary form is 맹랑하다, and the official LILYBYRED shade is literally “07 맹랑한 체리인 척” (pretending to be a cheeky-clever cherry).
