job security
     
         When some piece of code is written in a particularly
        obscure fashion, and no good reason (such as time or space
        optimisation) can be discovered, it is often said that the
        programmer was attempting to increase his job security (i.e.
        by making himself indispensable for maintenance).  This sour
        joke seldom has to be said in full; if two hackers are looking
        over some code together and one points at a section and says
        "job security", the other one may just nod.
