We had screw your sister date parties as well. They were so much fun

But nobody really got screwed, although we'd say "I'm going to find that hideous guy you hooked up with that one night at XYZ!". I know, that's harsh, but we were college kids then. In the end, we always ended up with someone we liked, and nobody really screwed anyone

It was also really helpful for the shy girls who would never ask a guy they liked to a party. Always a good party!! I recommend it to any sisterhood who is totally cool with each other. I wouldn't advise you to do it if you have dissention in the ranks though...could get ugly
