The Circle
If you thought the names were bad, you're in for real trouble now. The circle brings 3 things to most hashes: bad/naughty/bawdy songs, down-downs, and accusations.
Circle may start with a song or a toast to G (the founder of hashing). Then the RA will probably start doling out down-downs for virgins (people who are hashing for the first time), six week wankers(hashers who haven't showed up for 6 weeks or more), autowankers (people who did part of trail by car), and many more categories. As people get called into the circle, they may plead their case or just accept their beer, then, as the rest of the group sings a song to them, they chug their beer until it's empty (or pour it on their heads) and exit the circle.
This is followed by accusations. Someone raises their beer (usually resting it on their head) to be called on and, when they have the floor, they can accuse other members of offenses on trial. Offenses are varied and get crazier as more beer is consumed. (The RA's job is to keep some semblance of control in the circle.) The accused, usually found guilty, will then enter the circle and drink as the crowd sings for them.
