A girl that is usually very trashy and slutty. they usually wear torn leggings/stalkings (mostly of the fishnet variety) Most of the time you can find these creatures in urban areas where there is an abundance of drugs and pimps. ratchets usually surround themselves with other ratchets as if they are a primal animal searching for their next fix whether that be drugs or a penis that will provide food, shelter and drugs for them. most ratchets names are shelby's or mariah's. the most interesting thing about these things are that they usually love to twerk and "get down" at the club. A life that revolves around prostitution, drugs, alcohol and twerking, ratchets are very short lived specimens but still make the most of it in every which way they can.
