When Ronda Rousey went to a packed theater to see the film “Juno,” she had plans for a low-key evening. And when the group behind her talked throughout the movie, and the girl sitting behind her put her feet on Ronda’s chair, even nudging her head with her foot, she stayed calm, even asking the girl to stop. But when the movie was over, Ronda had had enough. She took the girl’s boot off her foot and threw it. She told the girl to get some manners. The guys in the group cornered Ronda in the theater and demanded she return the boot. When she didn’t, they push her against a wall. And that’s when the group found out they had been messing with the wrong woman.
