So Richmond is a city in California where Malik and Tasha are from. Referring to him as rich man is Franko's method of insinuating that he's never really had to struggle. He refers to himself as a gunman in an attempt to validate himself as the tougher of the too and shouts out his hood Get Some (which is presumed to be San Diego).

The Fonz was a character on celebrated TV series Happy Days who was known for his ultra-cool demeanor.
