I believe Monday night is orgy night, Wednesdays and Sundays are Bi night.
I don't think they have "bi-orgy night" but I can only imagine that it pretty much occurs on Sundays anyway. (I've only ever been on a Saturday which is strictly couples and male / male interaction doesn't happen except by accident.)
