I like to eat with fat chicks because I feel less bad about myself watching them stuff their fat porky faces.
Second: No, fat chicks never go away. Many fat chicks don't even know they're fat. They think they've got a good chance with you. In order to escape you'll need some popcorn chicken. Throw the box of popcorn chicken at the fat chick. Make sure the top is open. The chicken will scatter and she'll be forced to decide whether or not to chase you or try and beat the 5 second rule. The food will win, and you should make your escape.
