well i think that "blackjack" words came from this lyrics : GD be the ace; CL, she a queen Have 2NE1 they black jack; beat that Big Bang in your face pow; now take that We the leaders of the new school, how you love that {G-DRAGON ft Teddy & CL; The Leaders lyrics} BLACK JACK !!
it's a cool name as cool as with our idol 2NE1 btw, what's the fans club official color ?? xDDD
