Parading around Los Angeles
High off coke with a banana clip
Feasting off the weak street evangelists
The film is set in Los Angeles, and Harris is not only a drug dealer but a drug taker (high off coke), who uses his position as a cop to make money off of local thugs and dealer in street gangs (Feasting off the weak street evangelists). A Bannana clip is slang for a large clip for an automatic weapon.
