Help coming out to bigoted friends?

So, i go to byui (byu schools are owned and operated by the mormon church) and i recently realised my sexual preferences and am wondering how should come out to 2 of my closest friends. Their my roommates and I think they should know. They don't have many gay friends and they make a lot of rude gay jokes, and I just have no idea on the best way to just tell them I'm gay. They're not typical Mormons, but just don't know how they will take it. Help?
