Things are showing up in my Facebook feed that I don't subscribe to

Other than the fact I can't mute or use groups, the Facebook part is cool. But I'm getting things in my feed that I don't subscribe to. What is Sorority Life and why is it showing in my Facebook feed. I checked and I am not a fan and I have blocked the application. So why is it showing in my feed? Is it there because you think it's something I should be interested in?
