A sexual act in which a man and a woman have unprotected sex while she is on her period. The man ejaculates while inside her. She then squats over the man's erection and squeezes out the mixture of cum and menstrual fluid. Having coated the man's boner in such a manner, she then performs fellatio. The act resembles dining at a German restaurant where a bratwurst may be served with a warm red cabbage sauerkraut.
Screwing Sally on the rag made me nervous we would make a mess, but she just wanted some hot red cabbage and cleaned everything up.
