TLA /T-L-A/ n.

[Three-Letter Acronym] 1. Self-describing
abbreviation for a species with which computing terminology is
infested. 2. Any confusing acronym. Examples include MCA, FTP,
SNA, CPU, MMU, SCCS, DMU, FPU, NNTP, TLA. People who like this
looser usage argue that not all TLAs have three letters, just as
not all four-letter words have four letters. One also hears of
`ETLA' (Extended Three-Letter Acronym, pronounced /ee tee el
ay/) being used to describe four-letter acronyms. The term
`SFLA' (Stupid Four-Letter Acronym) has also been reported. See
also YABA.

The self-effacing phrase "TDM TLA" (Too Damn Many...) is
often used to bemoan the plethora of TLAs in use. In 1989, a
random of the journalistic persuasion asked hacker Paul Boutin
"What do you think will be the biggest problem in computing in
the 90s?" Paul's straight-faced response: "There are only
17,000 three-letter acronyms." (To be exact, there are 26^3
= 17,576.) There is probably some karmic justice in the fact that
Paul Boutin subsequently became a journalist.
