American Academy Of Actuaries - AAA

It's really an unfortunate name when you think about it. First off, read the name quickly and you could mistake it for the "American Academy of Atrocities," (think: Keanu as Lear) which would have really downer conventions. Secondly, the abbreviation isn't much better: advertise for an AAA meeting and you could end up with a handful of hopeful alcoholics.

Naming issues aside, the AAA is a professional organization of actuaries, who are the people who work for insurance companies and figure out how likely you are to die in a given period of time when you apply for life insurance. So their meetings might take some dark turns anyway, even without the possible name confusions coming into play.

The AAA is based in Washington, DC, and boasts nearly 19,000 presumably very dour members.
