a. A gathering of many people in which the only reproductive organs in the room are bratwurst. Commonly known as the "Sausage Fest."

I was promised by my friend that he would have many bitches at his party. When i got there i was upset to see that it was just another Braut-O. It was the Braut-O of the year.
