I went to a school for a year that was 85% greek. There was a fat chick sorority, a dork frat, a rich kid frat, a preppy assh0le frat. Many of the sororities had an alliance with a particular frat, and would basically be their slvts. I was pledge class president for the stoner frat. I went through almost all of a semester of pledging and all the stupid hazing. But I quit because I had started living with a gf off campus. When you're already getting laid twice a day, doing stupid sh!t for a club that is supposed to help you get laid seems pointless.
For the frat hazing, a lot of it is lining you up at attention and screaming at you. I grew up getting screamed at by parents and coaches, so that didn't bother me at all. That's why the other kids voted me to be leader. I was the one who wasn't scared of the hazing bullsh!t.
The frat would make you learn all sorts of trivial stuff about it and the other members. They had one night where they brought in an alum who was their intimidator. Before there was UFC, there was what they called "tough man" competitions. It was like UFC with less rules and no weight classes, fight tournaments for cash. This guy had just won the tough man in a Florida town of 100,000 people. He was a legitimate badass. He wasn't even very big, just a crazy mother fvcker.
Two of our pledges were best friends from high school and pretty dorky. While he was screaming at us, he zeroed in on them and started calling them gay. He wasn't letting up, and I could hear them about to start crying. I'm thinking I'm the leader and I have to do something. Leader of the pack fights the stray dog.
Then he tripped a little over one of the cords to the lights they were shining in our faces, and said, "damn, I must be a dumbass for not moving that light...any of you pledges think I'm a dumb ass?"
I took one step forward, and screamed at the top of my lungs SIR YES SIR. THIS PLEDGE THINKS YOU ARE A DUMBASS, SIR!!
Then there was a sound like the wind whistling through the trees. It was fifty guys sitting off in the darkness all gasping at once. The guy got in my face and told me something about the ditch he was going to dump my dead body in. As soon as he could see I was petrified of him, he immediately dropped it and moved on, and left those two kids alone. The funny thing was that he was the only one who could see how scared of him I was. I had several sorority girls come up to me that week and ask me if I was "that guy who called Johnny ___ a dumbass."
The girls do similar hazing, but I think the hot girl sororities like to line the pledges up naked and rip on their bodies. They make 18-19 y/o girls stand at attention naked while they walk by with markers and make marks on whatever body flaws they see. That's what keeps it a hot girl sorority - they haze out the fat and ugly girls. The frats would try to haze out dorky guys, all except the dork frat. My frat president told me, "you don't need to be hazed. But look at those other guys in your pledge class - they need some hazing."
