J stands for Junkie. The term is used down south often... even in rap songs. A junkie is somebody who has a bad drug addiction.
-Yesterday I saw a J giving head for some crack. That shits fucked up!

-T.I. - 24's:
By tha niggas getting head from a J, loose your leg when I spray and your dead from decay, stay ready for the raid pay heavy for the yay I told my class kiss my ass i make 11 everyday

-JR Get Money - Trap All Day:
Im in the trap all day, cell phone ringing off the hook from the J's, the blow sitting mad counting money in the shade, there sure aint no other way id rather get paid.
