For those cats who haven't heard the joint, here is the YouTube link to it:

"No more will you spit in my drinks, no more will you poison me"

I think this is a reference towards his time in prison were he was seriously abused and beaten up.

"No more will you poison me"

Again, a reference to cats trying to poison O.D.B. while he was locked down.

"I'ma climb real high feel free with the thug inside, no more will I run and hide"

This is Ol' Dirty saying that essentially he will not compromise his vulgarity on a track anymore (not that he ever did in the first place). He will not run and hide he will make a stand.

"No more will I chase the jug"

Not quite sure about this one, if anyone has any suggestions please say.

"No more will I go on the slug"
