Mud globb is the nasty, not even close to decent looking or smelling for that matter nasty version of a dirt rock. He/she is the friend that goes everywhere with the dirt rock that you ask your homie to sacrifice themselves to the mud globb for you to be able to get dirty favors from the dirt rock if you feel like it at your own will.
