The movie is called The Upside of Anger. The mother's daughter is having an affair with an older guy and is using him to get her a job on his radio or tv network. He tells the mother why he doesn't like women her age. He says when he takes a young girl out to a steak dinner she calls it "yummy." He also went on to tell her a few other reasons as to why he likes younger women.
This was a great movie.
