Slang term regarding a semi-legitimate business of contraband. Contraband being an act that bridges the gap between economies because though you may arrest people, others will rise up and some will make up new words for the industry like "riding dirty"....which is really jsut a cheap attempt at a rapper with no talent and alot of funding to "rise" to the top, if you will.
You know Run DMC??? they were IT.....they were good...or Sir Mixalot....see, that's classic, but this bullshit...it just sounds bad. Plus i mean what the hell, if you really want to make money without working hard and get women....you get a PhD.....it's actually not too hard.....gullable women will admire you and most of the work is on your own timing......you show up at work at 2pm.....or not at all if you dont feel like it. Then when your done you will likely get promoted and work alot less then a gangster and make maybe 6X as much. And women will want to fuck you, because your a "Dr." and they think that it's the shit.
That's where it's at FOOL!
Riding dirty is for pussies....the real playa's get the "Dr." then they get the women and the moolah....sucka.
