What BTS stands for

BTS is the most popular K-pop boy band. They have over 200 million fans around the world and growing. Yet many being new to BTS and K-pop don't know and ask what the group name "BTS" stands for. So here's the answer: BTS is the initial of the group's Korean name "Bang Tan Sonyondan (방탄소년단 in the Korean alphabet 'hangul')." "Bang (방) tan (탄)" means "bullet-proof": "bang (방) = proof/ward-off," "tan (탄) = bullet." "Sonyon (소년) means "boy" and "dan (단)" means "corp" or "scout," making "sonyondan (소년단)" together mean "boyscouts." So their name BTS means the "Bullet-proof Boyscouts."

Bullet-proof they are indeed. Hence so suiting is their fandom name ARMY.
