Crack heads to say the least, lol. Crack is also known as "hard". Atticts are known as "heads". Put the two together and guess what? You bet ya. Hardheads! Also, people call actual rock fish hardheads and croakers. So i think "Rock Fish" fits the same subject lol.
Boy Tyrone and Bingham sure are some hardheads! They'll do whatever it takes to get that hard. They like rock fish. Look at em' go!
