Nothing particularly outrageous. I went to clubs with friends when I was at Uni. A bunch of us who didn't engage in the drinking/dating culture. We'd go to the student union on student nights for a little bit, then grab some halal takeaway on the way home and watch films until the early hours.

I do however have quite a few friends (male and female) who have been through some things and turned their life around in their mid/late 20s. People who found a stronger faith in Islam later in life, or had bad experiences and then turned to Islam for guidance and help. So if I meet a girl who I feel I'm compatible with, and she has a past but isn't about that life anymore, I'm not going to immediately NOPE.

A friend told me about one of his relatives who didn't really pray, he didn't always eat halal, he drank alcohol and all that sort of thing. He met a girl from a religious family, they hit it off and she accepted that he wasn't really a practising Muslim at that point in his life. However, she and her family only agreed to the rishta if he moved in with her family. He agreed, and within a couple of years of being in a practising Muslim environment, he chose to start praying, and ending up doing his first full Ramadan of fasting in Mecca.
