Seven Dirty Words

The seven dirty words (or "Filthy Words") are seven English-language words that American comedian George Carlin first listed in 1972 in his monologue "Seven Words You Can Never Say on Television". The words are: 

shit 
piss 
cunt 
fuck 
cocksucker
motherfucker 
tits 

At the time, the words were considered highly inappropriate and unsuitable for broadcast on the public airwaves in the United States, whether radio or television. As such, they were avoided in scripted material, and bleep censored in the rare cases in which they were used; broadcast standards differ in different parts of the world, then and now, although most of the words on Carlin's original list remain taboo on American broadcast television as of 2015. The list was not an official enumeration of forbidden words, but rather was compiled by Carlin. Nonetheless, a radio broadcast featuring these words led to a U.S. Supreme Court decision that helped establish the extent to which the federal government could regulate speech on broadcast television and radio in the United States.
