While the term may have originated by Limbaugh encouraging people who enjoyed the show to just say "ditto", the word has now evolved to mean a blind follower of Rush's twisted logic.
A true dittohead would follow Rush Limbaugh blindly into the depths of hell if they thought he would allow them to touch one of his Oxycontin stained fingertips.
Bob: Rush Limbaugh is such a visionary. I would give my left testicle to share my Oxycontin prescription with him.
Steve: Why man, Rush Limbaugh is worth $500 million that the government knows of. He can afford to buy a child from South America and pay his way through medical school just so poor little Emanuel Limbaugh will be able to someday write Rush whatever prescription suits him that day.
Bob: Wow Steve, you are an idiot, Rush is just like you and me!!! He knows what's best for the people!!! HOW DARE YOU INSULT MY GOD!!!!
Steve: Sorry man. (Walks away)
(Bob remains infuriated for days not realizing that he's a typical "dittohead")
