A man, mostly like to be called 'Kez', who takes all of the skill out of football simulation console games by running as fast as possible towards the goal line and then cuts the ball back for a player to tap in from 2 yards.
The word jobber is derived from the type of goal scored here, a 'jobber goal'.
That's such a jobber goal Kez, you bloody jobber!
You been to the job centre there....
