The best overall college beer. Good taste, yet you can drink it till the sun comes up, and its only like 13 bucks for 30 of them.
I woke up at 1pm and drank keystone till 6am while smoking blunts of the chronic every couple hours but didnt pass out because keystone allows you to consume record amounts of beer and feel fine the next day.

He was so keystoned he couldnt even walk.
After two bowls and 8 keystones, he was keystoned out of his mind.

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