You gotta love geek talk.

I mean talking like a pirate might be fun, but talking like a geek is more, you know, fulfilling. And there are a wealth of geek terms to salt a conversation with: among my favorites are fud ("Fear, Uncertainty, and Doubt"; used originally by IBM and later by Microsoft and others to frighten prospects into buying their products), Gnu ("Gnu's not Unix"), cruft ("excess; superfluous junk; used esp. of redundant or superseded code" or the stuff that collects under your bed), foo (the canonical metasyntactical variable, or whatever you call the first thing on a list if you don't have any other name for it), and mung ("Mash Until No Good").

Jacob contributes another:

TWAIN is a standard for acquiring images from image scanners: an image capture API for Microsoft Windows and Apple Macintosh operating systems. The word TWAIN is not officially an acronym, however, it is widely known as an acronym for "Technology (or Toolkit or Thing) Without An (or Any) Intelligent (or Important or Interesting) Name."

Cool!
