How Well Do You Know English Slang?
(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.
