Wurstzeit is the time of month when men gather to have a sausagefest (crazy orgy). From german Wurst (=sausage=dick) and zeit (=time). Wurstzeit is common in Norway, England and Germany for both old and young men. In a way it's an nonchristian option for confirmation. To this date no women have ever heard of Wurstzeit, so it is a secret fest for men only. The fest is held every full moon.
Oh boy! Wurstzeit is next friday! I can hardly wait!
