Among other people, usually GDI or those in the north, fratty refers to a differently held stereotype of a frat guy. Such stereotype includes abercrombie t shirts, spiked hair, tribal tattoos, cargo shorts, popped collar...things that southern "fratty" guys actually find ridiculous, especially collar popping.
