Is a mechanic who works on drilling rigs. They are called pigs because they are always wallowing around on the ground or rig floor working on things. When they get up, they are covered in oil based mud. A motorman is a good example of a rig pig. He is usually the most dirty person out there.
Call a rig pig to come fix the ST-80. The roughneck will just mess it up worse.
