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.
