One who is employed in the oilfield that lacks motivation, self respect, integrity, and knowledge of what the fuck is going on around him/ her. The person usually lets everyone else do their job for them. They NEVER apply any effort, and make up excuses to get out of working. Like: "I cant pull slips because I get dizzy when I look up" or "I feel wierd so I have to go home". Sometimes the person will stop applying effort, and let their coworkers suffer, and finish the job. Typically Rackers, or want to be cases.
