Jersey Shore Question

Does anybody know why Ronnie hates Sam so much? She's smoking hot, she worships the ground he walks on and dotes on him nonstop, no matter how late he stays out clubbing it Miami-style with MVP. And yet all he ever says to her after he gets a few vaginatinis in him is "I hate you so fucking much!" while she stands there and takes it before dragging him home and giving him a rim job. What the fuck? Does anybody know what's the reason for this vitriol? And why would MTV be hiding such juicy info when it hardly seems like them to cover something like this up? These people don't miss a chance to film Snooki shaving her balls; I find it hard to believe that in this case they're like "whoa, whoa guys - none of our business. Let's give Sam & Ronnie the privacy they deserve here."

I mean, seriously, what's The Situation?
