30 stone 

A 30 pack of Keystone Light. Keystone Light is the beer of choice for college kids since its cheap and tastes much better than Natty Light.

A 30 Stone used to cost $10.99 but now its $11.99.

We got hammered last night, in fact I'm pretty sure we went through 4 30 Stones.

30 Stone Challenge 

When a person buys a 30-Pack of 'Stones (Keystone Light) and attempts to drink them all in a set amount of time.

Guy 1- Man, Ryan really tried his best at the 30 stone challenge!!

Guy 2- Yeah, especially since we only gave him 1 hour.

Guy 1- I'm just glad we don't have to clean up that bathroom after he's done...

A measure of the drunkeness of D-Bag in relation to the number of 12 oz. Keystones consumed in a period of time.

D-bag drunk dial: Call 1-800-ATT and get some assclown over here to get me out of the manhole. I'm 30 stones in, and I'm TANKED!!!
