ratchet 

A ratchet is one that may have a 1/8 tank of gas, his/her car is about to get repossessed but they still put rims on it that cost more than the actual car, don't have nor want a job, will stank a fool, rent is late, water already cut off, but they will still hit up the Koko and spend 3 stacks. True Ratchets love that Cajun Daquiri all day happy hour (Thug Passion, Pimp Juice) and Southern Classic.

Keep it ratchet.
