YAFIYGI
     
         /yaf'ee-y*-gee/ You asked for it, you got it.
     
        The command-oriented {ed}/{vi}/{nroff}/{TeX} style of {word
        processing} or other user interfaces which are not {WYSIWYG}.
        What you actually asked for is often not immediately apparent.
     
        This precise sense of "You asked for it, you got it" seems to
        have first appeared in Ed Post's classic parody "{Real
        Programmers} don't use Pascal"; the acronym is a more recent
        (as of 1993) invention.
