Sopornos 5: The Trouble with Women(2003)

Apparently Bobby Soporno can't catch a break. His prize fighter decides that he won't take a fall, so Bobby is forced to replace him with a hot new prospect who will gladly play Bobby's game for a nice cut and a hot piece of ass. Then, just when it all seems like it's going to come together, Bobby's screeching sister and lesbian mother start harassing him and try to teach him some family values he's not so willing to learn.
