In my Greek life days it seemed to be about 40% but that’s selection bias and i was deep in the ‘know’. After graduating if the girl wasn’t getting married many of them went even sketchier then they were in college.

We also found a shit load of them on sugar daddy sites. One girl got outed by her sorority and the kicked out....so a bunch of us got curious. Upper class girls in sororities where less likely to do it, sports chicks as well. General student body was way different

And that’s just what i saw who knows what was in the DL.
