Someone who actually doesn't care what anyone else thinks, because they go out in public with little to no effort to look presentable, or look like anything for that matter. Their clothes are typically cheap and ill-fitting, and they wear sweatpants because they are the most comfortable thing it is legal to leave the house in.
