What does 미친 mean?
미친 (michin) is the modifier form of 미치다 (michida, "to be crazy"). On the surface it means "crazy," but in everyday slang it has flipped to mean "amazing," "insane," or "wild" — much like English "this is sick" or "that's nuts." 미친 + noun is the most common pattern: 미친 노래 ("an insane song"), 미친 실력 ("crazy skills"). As a standalone exclamation ("미쳤어?" = "Are you crazy?") it can be sincere, mock-shocked, or playful. K-pop fans use it constantly. The literal "crazy" meaning still exists, so context decides whether 미친 is praise or insult.
