On the shop floor, this describes components that have been warped out of tolerance by excessive force, heat, or misuse. It can also refer to a procedure or rule that has been deliberately bypassed or corrupted to get a job done faster. When a tool or part reaches this state, it usually requires replacement rather than repair.
