The most enjoyable priesthood socials I've been to have been something simple and enjoyable - like a BBQ in someone's backyard.

We've also played basketball, flag football, and even had a board game night.

I've found the best Elders Quorums do things that are enjoyable and allow everyone to participate, and some regularity. The regular schedule seems to help as people have more and more experiences together, they grow closer together.

Also, our ward is very good at moves - they are almost a social event in themselves
