Brolio

A condition found in gyms and fitness clubs where a bro with a massive upper body habitually skips Leg Day in order to keep his pumped state in the region of his upper body.

The resultant lack of fitness to the legs leaves the Bro deformed with a monstrous upper torso and arms with tiny little old lady spindly legs.

Oh, man, Scott (because all Bros are named Scott), really has The worst case of Brolio that I've ever seen. I don't think his legs have ever done anything but walk his ass over to the dumbbell rack.
