keystone friend 

The person in a large gathering of strangers and acquaintances that knows everyone and brought them together.

I went out to a bar with my friend John and a bunch of other people I didn't know. It was some people from John's work, a few of John's college roommates and one of his friends from home. We all didn't know each other, but John was the keystone friend.

Keystone Lighting 

Similar to how every cloud has a silver lining, every picture of drunks has a can of Keystone light in it.

Tammy: My picture doesn't have Keystone Lighting in it because it's just of my face.

Mark: Yeah but you can see a reflection of a can in your pupils, and your face says it all.
