Describes the command-oriented ed/vi/nroff/TeX style of word
processing or other user interface, the opposite of WYSIWYG.
Stands for "You asked for it, you got it", because what you
actually asked for is often not apparent until long after it is too
late to do anything about it. Used to denote perversity ("Real
Programmers use YAFIYGI tools...and *like* it!") or, less
often, a necessary tradeoff ("Only a YAFIYGI tool can have full
programmable flexibility in its interface.").
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.
