Dark secrets and embarrassing moments people would rather not speak about again. These can range from smaller things like adultery to bigger like rape. Whatever the 'body' is, it is a dark memory the person would rather people never found out about. This phrase tends to be used with rich middle eastern people who are obsessed with cars.
