Common four-letter words (in this sense) that are widely considered vulgar or offensive to a notable degree include: cunt, fuck (and regional variants such as feck, fick and foak), jism (or gism), jizz, shit, twat and tits. Piss (formerly an offensive swear word) in particular, however, may be used in non-excretory contexts (pissed off, i.e. "angry", in US English and British UK English ; pissed, i.e. "drunk" in UK English) that are often not considered particularly offensive, and the word also occurs several times with its excretory meaning in the King James Bible. Several of these have been declared legally indecent under the United States Federal Communications Commission (FCC) TV and radio open-airwave broadcasting regulations.
A number of additional words of this length are upsetting to some, for religious or personal sensitivity reasons, such as: arse (UK), damn, crap, hell, piss, wang, and wank (UK). Racist, ableist, and slurs pertaining to an individual's sexual orientation may also qualify, such as mong (in the UK not a racial slur, but short for Mongol, or someone with Down's Syndrome - previously called Mongolism), gook, kike, spic, coon, dago and dyke. Several "four-letter words" have multiple meanings (some even serving as given names), and usually only offend when used in their vulgar senses, for example: cock, dick, knob, muff, puss, shag (UK) and toss (UK). A borderline category includes words that are euphemistic evasions of "stronger" words, as well as those that happen to be short and have both an expletive sound to some listeners as well as a sexual or excretory meaning (many also have other, non-vulgar meanings): butt (US), crud, darn, dump, heck, poop (US), slag (UK, NZ, AUS), slut and turd, as several examples. Finally, certain four-lettered terms with limited usage can be considered offensive by some, within the regional dialect in which they are used, such as mong and mary.
Occasionally the phrase "four-letter word" is humorously used to describe common words composed of four letters. Typical examples include the word work, implying that work can be unpleasant, or the game of golf, jokingly referred to as a four-letter word when a player's pastime becomes an exercise in frustration. Charlotte Observer journalist Doug Robarchek noted in 1993 how many politicians have names with four letters, "Ever notice how many U.S. politicians have names that are also four-letter words? Ford, Dole, Duke, Bush, Gore . . . and how many make us think of four-letter words?"
