Dittohead

A dittohead is a person who likes but does not necessarily agree with The Rush Limbaugh Show. Faithful listeners to the show claim that it is a mistake to think that "ditto" means that the caller agrees with Rush Limbaugh's opinions.

Saying "dittos" (or even "mega-dittos") was started by a Rush Limbaugh caller as a shorthand way for callers to say they like the show and to save time.

The term has been used as a snipe by people who disagree with Rush Limbaugh groupthink.
