So when you see them folks, don’t forget to warn a brother
The twisted society may of course want to take someone under, in this case you should warn a “brother”, which is B.o.B., while “folks” are the police, a.k.a. who are trying to take him under as told is the previous line.
“Warn a brother” and “folks” together also refer to the Warner Brothers cartoons, which always ended with “That’s all Folks!”
