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)
