(1) Ridin' dirty refers to the act of riding on Las Vegas public transportation (namely the Deuce Bus) for an extended period of time without travelling a great distance.

(2) The act of partially soiling one's underpants and continuing to "ride dirty" as though nothing had happened.
Person 1: We've been on this bus for like 20 minutes and we've only gone a block.
Person 2: Ya, we're ridin' dirty.

OR

Person 1: "I think I might be ridin' dirty."
Person 2: "Seriously"?
Person 1: "I dunno, I might be."

chamillionare's song
here is the properenglish version
ridin dirty

they see me rolling
they are strongly disliking
they are doing their rounds and they're trying to catch me driving with uncleanliness
trying to catch me driving with uncleanliness (x4)
my music is so loud
i am swinging
and they are hoping that they are going to catch me driving with uncleanliness
trying to catch me driving with uncleanliness (x4)

A song by Chamillionaire about how the cops are out to get him because of his race. Well...simply to me...to put it into simpler terms...the lyrics are:

They see me rollin
They hatin
Patrolling they tryin to catch me ridin dirty
Tryin to catch me ridin dirty
Tryin to catch me ridin dirty
Tryin to catch me ridin dirty
Tryin to catch me ridin dirty
My music sold out
I'm swangin
They hopin that they gon catch me ridin dirty
Tryin to catch me ridin dirty
Tryin to catch me ridin dirty
Tryin to catch me ridin dirty
Tryin to catch me ridin dirty

BUT!
Here's what it should be instead of Ridin Dirty:

They gaze upon me driving, They feel a pang of strong dislike, Following my car attempting to view me driving with uncleanliness, Attempting to view me driving with uncleanliness x4.
The music I have made is selling large amounts of tickets, I am very rich, The cops are praying that they may view me driving with uncleanliness, Attempting to view me driving with uncleanliness x4.

For the people who don't understand the new SLANG
