I don't think you're looking for an accent. It sounds like you're looking for slang and dialect. Very different things.

"Accent" would be having someone say, "Oy doen't loik it atawll! Nao, suh, noh atawll!"

Slang/dialect is stuff like saying "chips" instead of "fries," or referring to your face as your "Chevy Chase" if you want to get into specific dialects like Cockney Rhyming Slang.
