Where pledges made to do sexual stuff and the like.
Try rlfj's "A Fresh Start;" Chapter 29 has some fraternity hazing:

And Chapter 49:

That is very much NOT shown as sexy. 'A Fresh Start' has the MC addressing the aftermath of realistic sexual abuse hazing and it's not shown, much less presented as a positive thing.
The series An Ordinary Sex Life has several stories set during the time the MC is in college. I think at least the last two of the college life includes interactions between the MC an a sorority.
One of them is called "OSL: Pledge Initiation"
