Used to describe the long-term affects on someone who uses crank (methamphetmine). Often the person will be sickly skinny, with dark circles around their eyes, cuts and scabs in varying parts of their body and look, sometimes drastically, prematurely aged.
"When I came back into town I was gonna hit up Steph, but she looks horrible now man, a real crank monster."
"Yeah dude she used to be hot..."
