Cover art for Low Rider (War cover) lyrics by KoЯn

It's a cover version of War's Lowrider. Can anyone tell me what's the meaning of el caco? Right before Helmet in the Bush there can be heard something similar to "don't call me caco". It goes on a little while. What does it mean?

Is Head called "caco" sometimes?
