Uh, go to a different college. You get kicked out or whateva for looking too girly? What? The guys there are all flat and no one has heard of man boobs and won't be your friend if not. I have had plenty of close, best guy friends and I have always had B cup boobs on a really tiny frame since, well, puberty. I would move to somewhere more accepting. That would be first. As far as hiding them,get a sports bra and put an A-shirt over them. An A cup, or a bust 1.5 inches above your band size which is what I assume you mean by A 1/2, are really not that big, all things being considered. And by big, I mean, incapable if being hidden.
