I have NO clue abouat how this got started but we do blue boobs at the end of the meeting... its when we get to say something stupid or embarrassing about something that happened to us- or we can call another sister out and tell about soemthing dumb or funny THEY did- its hysterical and after mixers or big party weekends they last forever- also- at the beginning and end of the meeting we do a ceremonial clap thing that we have to learn- its really fun when we get it right- and its fun even when we mess up b/c we all start laughing- the blue boobs are definately my favorite and its nice to do them at the end esp when the meetings are tense or boring
