DA means district attorney. The relevance of this and urban terminology is it'
s connection with punishment for crimes. If you get caught by the 'Po (
police for yall) selling
drugs or whatnot, you will probably have to deal with a District Attorney. District Attorneys only practice law in district courts (imagine that). If you
murder someone or get caught with enough coke to make a state, or even worse, a federal case, you won't be dealing with a DA, you'll be fucking with a whole new ballpark of lawyers and attorneys.
My homie Broham is in and out of
court for possesion of narcotics and unlawful carrying of a concealed weapon. So, me and
big 'Maal are about to show that fuckin DA how my
strap works.
