In places where the fermented hops is expensive as gold, it's a good thing to wind up the ol' party mood with your friends at home. You drink, laugh, exchange wild stories about your glorious past and then hit the town.

There's a strong segregation between women and men, and thus you have women-vorspiels and men-vorspiels.
