"BDK" (Black Disciple Killers) also known as "GD" (Gangster Disciples) is a gang in Chicago. Rappers such as Lil Jay, P. Rico and Lil JoJo who was shot and killed at the age of just 18 by the Black Disciples, are affiliated with the gang. The gang is also known as BrickSquad, FBG (Fly Boy Gang), and Tooka Gang after fallen member Shondale "Tooka" Gregory

The Black Disciples, also known as GDK for "Gangster Disciple Killers", are a rival gang to the Gangster Disciples, thats why they call them selves the Black Disciples "KILLERS"!

You probably think you dont know anything about the Black Disciples, but they are a lot more popular then you think.
If you listen to rappers such as Chief Keef, FredoSantana, Lil Reese, SD, and Tadoe then you should have some idea of what the Black Disciples are. Chief Keef and his crew are a part of the #300 set of the Black Disciples. Rappers such as RondoNumberNine, Edai and L'A Capone who has also been shot and killed at a very young age for dissing a fallen member of rival gang BrickSquad, Shondale Gregory, are part of the #600 set of the Black Disciples. These two sets have very few beef with each other, if any, and rappers from both sets collaborate with each other to make songs.
"These niggas claim #300, bitch we BDK" - Lil JoJo
"Niggas talkin bout' 6'Double 0, wassup wit dem?" - Lil Jay
