This lil' gem originated in Watkinsville, Georgia in the year 2004. It is in reference to high power 12-gauge shotgun shells. They are easily recognized by the fact that the brass travels a good way up the shell, more brass equals more power, which equals more fun! Ideal for use in an AK-12.
Ryan: Jesus fucking Christ man. I feel like a horse just kicked me in the shoulder!
Drew: Well, when your letting high brass rounds slip out the AK-12, what do you expect?
