Sexual Intercourse.

Anton gets confused when he visits Thea at home the first time. They recently had great sex. But now it seems weird that the flatmate Paula knows all about that night with Thea. What does she mean with "Geh Vau", he asks. "Fucking," answers Paula. When he's ready to head out for a concert of the feminist punkband "Schapka", Thea would prefer to stay at home with the handsome young man.
