Show Muscles
When someone acquires muscles through going to the gym and only the gym. The physique is only used to show and to look good and does not serve a practical purpose such as manual labour (yes I know i used a u, I am British).
Person 1: Aren't they so hot with all those muscles
Person 2: yh but he's got show muscles, he hasn't done a proper manual labour job in his life
