Keystone Ice Cream 

The combination of chasing rum (preferably Bartons Gold Rum) with Keystone Ice. The result is a creamy concoction that resembles ice cream.

Mike - "Hey Kyle, are you tryin' to party?"
Kyle - "Hell yeah, let's get some Keystone Ice Cream."

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.

Will grow up to be the baddest female alive. Has the best glow up by the age 16. Usually eats lots of food but never grows. Grows up to be thicker than a Snickers. Every man wants her but only one gets her.

I wonder if Keyshondra like me ?

keystone 

A very inexpensive beer purchased and consumed by trailer trash and frat boys everywhere. Probably manufactured in prison toilets.

Matt: "Hey Ryan, I have a couple of bucks. Enough for some Keystone! Let's go get wasted and make out with each other!"
