If you want the purp step into my office sir
We can even share if you wanna chief
This is a double meaning throughout these bars.
First, lets look from the aspect of law enforcement.
Kenny has apprehended a perpetrator/suspect. Office Sir is a homophone for officer, whom he would hand the perp over to. In the second line, share if is a homophone for sheriff. Perhaps he is speaking to the police chief, offering to share information.
The other interpretation to these bars relates to marijuana and getting high.
