A term used to describe another person as in the way
people call each other dogs. It came from the Derby Lane dog track when a bum
bet on a dog and was so frustrated that he called the dog that lost a rat! We overheard this and every time we
bet a dog that lost we called him a rat. Then we started calling each other rats for betting on rat dogs. The term rat can be used as a compliment and as an insult. It all depends on how you use the term.
