Frustration manifests itself in a number of different ways.
One way is anger -- unfortunately for this lineman, we got to see it in full force during a recent football game in Kentucky.
This kid apparently thought that the lineman held his block a little too long and decided to retaliate in one of the worst ways imaginable.
And here's the wide angle for a sense of atmosphere.
Of course the official had his back turned, so no flags were immediately thrown on the play. But something tells me that after the release of this video, justice will be quickly served.
