Insult
From Wikipedia

An insult is an expression, statement or behavior that is considered offensive, rude or degrading. Insults may be intentional or accidental. An example of the latter is a well-intended simple explanation, which in fact is superfluous, but is given due to underestimating intelligence or knowledge of the other.Whether speech or behavior is insulting, in practice and sometimes by the terms of local assault statutes, is often a product of the subjective sense of the person insulted. But insults to one person who might not mind the derogatory speech may indirectly insult others. Many states and local municipalities enforce prohibitions against rude, offensive or insulting speech, leaving citizens, law enforcement officers and courts to decide what is and what is not an insult. The concept of fighting words as a form of prohibited speech has developed in the jurisprudence of U.S. constitutional law concerning terms of disparagement. But insults offered as satire in an artistic venue, such as a novel, a film or a song, are usually regarded as protected speech, especially in the United States.The role of insults in the social sense may be better understood by an appreciation of how the term is used in a medical setting. Though a popular idiom refers to "adding insult to injury," in a medical context they are the same. Physicians examine injuries resulting from an insult to flesh and bones, caused by various traumatic events. In speech and in social settings, insults are words that tend to injure the psyche. In humor, insults may be exchanged in much the way fighters exchange blows in training, to develop a resistance to the pain of mild injuries, or to spar with no real intention of seriously injuring the other.

sat·ire
Pronunciation:\ˈsa-ˌtī(-ə)r\
Function:noun
Etymology:Middle French or Latin; Middle French, from Latin satura, satira, perhaps from (lanx) satura dish of mixed ingredients, from feminine of satur well-fed; akin to Latin satis enough —Date:15011 :
a literary work holding up human vices and follies to ridicule or scorn
2 : trenchant wit, irony, or sarcasm used to expose and discredit vice or folly. Satire is strictly a literary genre, although it is found in the graphic and performing arts as well as the printed word. In satire, human or individual vices, follies, abuses, or shortcomings are held up to censure by means of ridicule, derision, burlesque, irony, or other methods, ideally with an intent to bring about improvement.[1]

Although satire is usually meant to be funny, the purpose of satire is not primarily humour in itself so much as an often quite angry attack on something the author strongly disapproves, using the weapon of wit.A very common, almost defining feature of satire is a strong vein of irony or sarcasm, but parody, burlesque, exaggeration, juxtaposition, comparison, analogy, and double entendre are all frequently used in satirical speech and writing. The essential point, however, is that "in satire, irony is militant"[2]. This "militant irony" (or sarcasm) often professes to approve the very things the satirist actually wishes to attack.
