You're sitting with your mother in a restaurant. Next to you sit a married couple, their son, and a girl. The boy introduces the girl to his parents. The girl is overweight, and the parents make it clear that they don't like the girl because of her body. Comments like "Is your mom Dumbo?" or "Did you eat too much cake?" come up.
