Nice site, but maybe you should take the vulgarity out of the captions of your photographs, and get rid of the hot dog thing.
What's funny to you guys, is not necessarily going to be funny to others visiting your site. Remember, your website represents your fraterinity, and is the first way many people will get impressions of you. Just maybe get rid of the swearing and stuff, makes you guys appear kinda immature and unprofessional.
Other than that, the site is awesome and well done.
Just a suggestion from an ex-sorority webmaster.
