Sorority House Massacre (1986)

The start of one of the more bizarre franchises in 80s slasher movie history, Sorority House Massacre (1986) starts when our protagonist Beth is a little girl and her older brother murders everyone else in their family, before being locked up. Beth survived, was raised by a different family, and is now played by Angela O'Neill, as she makes her way to college and pledges to a sorority. The only problem is, her murderous older brother has broken out of the institution where he was being held and has broken out to finish what he started over a decade earlier! 

Poor fraternity hunk Joe Nassi is one of the escaped brother's many victims, surviving one attack without his clothing, giving us a nice look at his ass as he runs back into the sorority house to use the phone! We wouldn't mind getting a little Nassi with Joe!
