Crack Fiend originated during the Hawaiian industrial revolution. It was used to describe the workers who had become addicted to crack due to poor working environments. Therefore, crack fiend has been passed down through the generations of Hawaiians and has morphed into a new meaning. It now is used to describe annoying people, as well as people addicted to crack. And sometimes, it is used to describe people who wish they were addicted to crack.
Crack Converters is the street name by which the establishment called "Cash Converters" is known. This is due to the fact that when a crack head has wogged electrical goods from your house he/she takes them to Crack Converters. Its an establishment doing crackheads and people on the dole a good turn.
Come on now we've both got our giro cheques from the dole office we can go down Crack Converters and score them Technics decks we saw Scaggy Pete with the other day.
