EACYPAA stands for the Eastern Area Convention of Young People of Alcoholics Anonymous (EACYPAA).
It's an annual conference, and it's always held somewhere on the East Coast (from Canada to Florida, between the Mississippi and the Atlantic).
Basically, thousands of young people gather in a hotel for a weekend. There are meetings and A.A. workshops, but there are also tons of cools events.
Previous EACYPAAs have included things like: karaoke night, drag & variety show. dub trap room, all-night pool parties, sober olympics, and more.
