From Plastic Tub

Abreviation and common form of Accidental Associationalism. Not to be confused with Alcoholics Anonymous, the Argentum Astrum or any other quasi-religious organization bearing these two initials.

"Although we speak of "The AA" and "AA'ers," it should be noted that "AA" has never represented any formally chartered or established group as such, but a group of individuals and groups so-chartered, bound together in a loose affiliation based on shared ideals and cameraderie."
--Lollop Whitley, Dogs for Checkers: AA Symboliosis and Distance Language, introduction to the 1986 edition, University of Kansas Press.

AA has also stood for Accidental Action, the Association of Association and the Associatio Amicorum.
