I think this situation is common in almost every larger dojo. The only thing you can really do, is concentrate on your own practice and try not to let this bother you. Just work on your own betterment and be polite and curteous to the frat boys. They are offering you a lesson in patience and understanding (of their immaturity in some way). If you let it get to you too much, it can ruin your love of the practice.
