Dittohead
From Wikipedia, the free encyclopedia
A dittohead is a fan of The Rush Limbaugh Show. (Dittohead is also the title of a track on the Album Divine Intervention by Slayer.)
Saying "dittos" (or even "mega-dittos") was started by a Rush Limbaugh caller in 1988 as a shorthand way for callers to say they love the program and for Rush to never quit doing the radio show.
The term has been used as a snipe by people who see it as an example of groupthink allegedly encouraged by Limbaugh.
