Koch-head is a slang term for a politician who is hopelessly addicted to the toxic drug called kochaine. Kochaine is highly addictive and is ruining lives at this very moment. Koch-heads are volatile, erratic and highly dangerous when under the influence. Never make an attempt to reason with or apprehend a koch-head, simply call 911 and you will be helped by a local, unionized, law enforcement expert.
That crazy Scott Walker...what a koch-head!
