What, pray tell, is a "road roach"?
I’m going to guess based on absolutely no knowledge.
Real “bikers” are hardcore Hells Angels or Pagans etc.
Road Roaches are the Wild Hogs type people.
A road roach is an individual or a group of individuals that ride motorcycle(s) individually or in groups that swarm in and out of traffic, drive recklessly, do “stunts” and basically give bikers, riders a bad rep.
Usually urban based crotch rocket squids.
