Obese Teenagers with Game?

Well, i go to high school and there a lot of obese male teenagers who are mad playas. I myself used to be obese, but i lost a lot of weight [ i am proud enough to call myself a winner]. But these guys are obese and have women! My good friend, she is smokin, and her boyfriend is huge! No offense, but how do all these large boys get chicks!? Personality? No that can not be it! There has to be some formula, some sick twisted mutation or equation, oh woe the insanity. Why do big boys score?
