The Bungie Acronym Compendium
JNAMSTFY. DMUKYA. ABTFIPASO5. These cryptic identifiers have entertained, enightened, frustrated, and confounded Bungie fans since the early days in Chicago. Found on nearly every game and soundtrack created or licensed by Bungie, a surprising number of these enigmatic acronyms remain unsolved.

There have been tons of different guesses as to these on a variety of different forums all over the place, so if you see one you think you know the answer to, feel free to post a comment. Hopefully, someone at Bungie will step in periodically and let us know how we're doing.
Remember that, although some of them contain a little bit of good-natured profanity, they're not
all strings of foul language. Many of them are catchphrases heard around the Bungie offices during development of the related game.
Note: It's pretty obvious that EGATFIBGBCSIMAW refers to the skulls (Envy, Grunt Birthday Party, Assassins, Thunderstorm, Famine, I Would Of Been Your Daddy, Blind, Ghost, Black, Catch, Sputnik, Iron, Mystic, Anger) but since no one from Bungie has ever stepped in with any observations on the elusive W at the end, and public opinion is hardly conclusive, it's pretty pointless to keep throwing guesses about it around. Maybe somebody in the know would care to tell us a story? ;-)
Update
For the record, here are a few of the more widely-recognized guesses on some of the unsolved ones:
SPMLOAS: Single-Player Myth, Loads (or Lots) Of Additional Shit
ILWNL: I Like (or Love) Winning, Not Losing
IOHBOY: I'm Only Here Because Of You
SIOHBOY: Sid, I'm Only Here Because Of You
Anyone who can confirm or deny these is always welcome. :-)
Another Update
In the Halo 3 Beta, SABABWL is heard via Morse code, coming from the radio near the upper flag base on the map High Ground.
