Originally part of the term "road hard and put up wet" in reference to horses. As in the horse was put through a hard workout and then wasn't brushed down and cared for afterwards, which can make a horse sick enough to die. Now used to refer to someone who looks unkempt, strung out, tired, dirty, etc.

road hard is a term that describes the way a particular thing looks, usually a girl, when it or she looks rather gnarley, respectively.
