You need to add a couple more categories
Schmoe: Doesn't necessarily train and often fat/obese, but is "interested" in bodybuilders bodybuilding
Tiny Tit: Doesn't lift heavy and looks like they'd lose the "Most Muscular" award in a concentration camp posedown, but discuss and give out advice on lifting & nutrition endlessly
Permabulker: Trains primarily for looks, but never diets down due to fear of being small or out of incompetence
Pumper: Upper arms and chest only, esp with synthol, implants, or site injections - sometimes calves too to help "complete the package".
