What are the names of 2NE1 fans?

after more than 1 days' long wait (Mr. Yang TAT), finally, our 2ne1 rice has an official title (scattering flowers ~ ` applauding ~`). According to the announcement of the official cafe, our name is Black Jack (such an artistic name, the person who worships the name). Black Jack is taken from Black Jack, a poker game. As we all know, there are two playing cards on our girls' uniforms, and the number of points displayed on them is the largest blackjack, and many children have long regarded this pair of playing cards as the symbol of girls, so they took this blackjack.
