I did Cardio only today and one of my friends in that gym who is from Romania and is friggen huge, not cut but really big after talking to me walked over to the Squat rack, when he was getting ready to do his first lift I saw some skinny 16 year olds imitating him by making fun of how he walks with his arms outstretched and a dumb face.
He did not see it and I know he has a temper (roidrage lol) and he probably would have smacked the fucker and would have lost his Gym account.
