From my experiences in frat houses...this is what comes to mind.
For the first year or two, sleep on a sleeping porch which may or may not have consistant heat. Bunks probably with a bunch of others. Dirty beds, dirty bathrooms, dirty kitchens, dirty hallways. Everything but the foyer is pretty much dirty. Giant kitchen where you can get food whenever. Parties on most weekends and often weeknights, too. Girls everywhere, some respectable ones at the more formal gatherings, but most parties will just be filled with the same girls that are in the slutty high school girls thread.
Brothers can help you study, and by study I mean share tips on ways to cheat.
