For those outside of the St. Louis region, Hoosier has a different definition here. I’ve seen people try and explain the meaning of Hoosier to people from Mexico and China with no luck. I now have a solution to explain what Hoosier means.
There may be a St. Louis connection as well. The kid is apparently from Blue Island, which pretty much explained everything to me when I heard it. Blue Island is a pretty rough refinery town–or it was until Premcor shut down its refinery. And everything is pretty much toxic in Blue Island because of the refinery (most of the damage before Premcor bought it). So on top of meth, there is a good reason these guys are morons.
A great take on the clowns is here at ESPN
