truth about sorority hazing or whatever ya call it

We all know hazing is completely banned and no sorority of fraternity would ever admit to it, but any of us involved in Greek life at all know that's not quitee true. I'm rushing this fall and am thinking either Chi O or Pi Phi to join, I don't wanna join DG because they don't really know how to have fun. My bf is a sig nu and my best friend is a pi phi so I'm pretty aware that hazing or initiation trials go on. I just want to know what some experiences are some girls have had pledging as far as those sorts of trials go, and don't skimp on any unpleasant details, I'll still pledge idgaf what I have to do for it.
