A moron that works on cars that does not have the mental capacity to properly diagnose any electrical problem if their scan tool does not give them the answer. This person typically says the problem is a loose wire, something is grounded out or shorted out, or blame aftermarket electronics for the problem without any real evidence.
The stupid mechanic said that my window won't go up because of a loose wire behind my radio.
