Here's another swell word:

"Asshole"

Asshole or arsehole (outside the U.S.) is a term referring to the anus. It is generally used as a profanity in expressing deep contempt for someone or to describe a particularly abrasive person.

This word is found in colloquial speech in a number of cultures (in both English and in direct translation to other languages). This is due to the fact that it describes an organ of elimination that is considered a taboo region (belonging to the intimate parts) of the body in many societies.

The English word ass (meaning donkey, derived from the same root as its zoological name Equus asinus) may also be used as a term of contempt, referring to a silly or stupid person. In recent years, the words arse and ass have become synonymous in the United States, however in the rest of the world, ass still only refers to the donkey, rather than the arse (buttocks). It is worth noting that some varieties of English drop the letter "r", leading to practically identical pronunciations of ass and arse.

Until the early 1990s, the word was considered one of a number of taboo words that could not be uttered on American commercial television.
