You can see the psychology at work in this thread. For the first time in a long time, Vince won and Galeniko lost. It all goes back to our school days and extends beyond. Vince is naturally endomorphic, and gets fat very easily. You can't see his muscle but looking at the arms, and forearms (the shirt covers up everything else) there is muscle under the bodyfat.
Galeniko is ectomorphic, and can't put on size. He resorts to pining himself with anabolics. Without the anabolics he looks like Justin Beiber. After Vince makes the comment, Galeniko melts down, and goes for the junior highschool homo angle as a basis of attack but goes overboard. So overboard, you know the comment bothered him because inside, he knows it is true.
At some point Galeniko goes off steriods and weighs 150 lbs with a 13 inch arms. Vince although fat, will be at 235 lbs with 18 inch arms. In the natural order of things whether in the schoolyard, bar, or gym, the bulky guy will get more respect then the string bean, all other things being equal of course.
