Dictionary.com's Word of the Year is...
/baz/ The third metasyntactic variable "Suppose we have three functions: FOO, BAR, and BAZ. FOO calls BAR, which calls BAZ..." (See also fum). Occasionally appended to foo to produce "foobaz".
Early versions of the Hacker Jargon dictionary derived "baz" as a Stanford corruption of bar. However, Pete Samson (compiler of the TMRC lexicon) reports it was already current when he joined TMRC in 1958. He says "It came from "Pogo". Albert the Alligator, when vexed or outraged, would shout "Bazz Fazz!" or "Rowrbazzle!" The club layout was said to model the (mythical) New England counties of Rowrfolk and Bassex (Rowrbazzle mingled with Norfolk/Suffolk/Middlesex/ Essex)."
