MLK Street 

This street is commonly inhabited by black folks, or more commonly know as the street all white people avoid by a mile radius to keep their mayonnaise safe.

Billy: You coming to the national BBQ convention?

Richard: Sure didly do! What are the directions?

Billy: 3 Miles on the 405 and take the exit onto MLK Street, lock your doors! You have no idea what those things will do?

Logan: Erm, I think I'll pass, I have a family I think I'll like to keep.
