Known Lazy Bastard
     
         (KLB) A term, used among technical support staff, for
        a user who repeatedly asks for help with problems whose
        solutions are clearly explained in the documentation, and
        persists in doing so after having been told to {RTFM}.
     
        KLBs are singled out for special treatment (i.e. ridicule),
        especially if they have been heard to say "It's so boring to
        read the manual!  Why don't you just tell me?".  The deepest
        pit in Hell is reserved for KLBs whose questions reveal total
        ignorance of the basic concepts (e.g., "How do I make a font
        in {Excel}?", "Where do I turn on my {RAM}?"), and who refuse
        to accept that their questions are neither simple nor
        well-formed.
