The list of banned words for US radio and television is in a U.S. Supreme
Court report called FCC v Pacifica Foundation (438 US 726,
57 L Ed 2d 1073, 98 S Ct 3026). The case was about a radio program called
"Filthy Words", sp[oken over the air on 20 October 1973, by a "satiric
humorist named George Carlin" (I quote from the
report at 438 US 729). The court report includes a transcript of the
The original seven words were shit, piss, fuck, cunt,
cocksucker, motherfucker, and tits.
Three more words you could never say on television were fart, turd, and
twat. Fart is harmless. It's like tits. Cutie word, no problem. Turd
you can't say, but who wants to? But "twat" is interesting ... Twat!
Twat is interesting because it's the only word know applying to a part
of the sexual anatomy that doesn't have another meaning. Snatch, box, and
pussy all have other meanings. Even in a Walt Disney movie, you can say,
'We're gonna snatch that pussy, and put him in a box and put bring him on
the airplane.' But twat stands alone.
(Incidentally, the UUS Supreme Court, by a majority, said that the
Federal Communications Commission could stop radio stations broadcasting
stuff like that, at times when children were likely to be listening, in
spite of the First Amendment to the US Constitution.)
What about euphemistic or 'hidden' references to 'forbidden' words,
such as the increasingly popular "X-word" form?
Forms such as "the f-word" (fuck), and so on, have now branched out
into politically correct usage, i.e. to cover words not considered
politically-correct in context.
Other examples include "the D-word" ("dynamic", used as code for "male" in
university teacher ads), or "the L-word" ("ladylike", as a counterpart in
the same article).
