A ridiculous term made up by Republican pundits in order to sell books to the right-wing echo chamber. The idea here is that fascists believed in big government, and so do most leftists, therefore leftists are the real fascists and no true right-winger could be a fascist.

Of course, people who don't watch FOX News hate fascists for being murderous, racist, anti-intellectual, aggressive, homophobic, authoritarian, and religiously bigoted, not for believing in big government.
