The Spanish language employs a wide range of swear words that vary between Spanish speaking nations, and in regions and subcultures of each nation. As in most languages swear words tend to come from semantic domains considered taboo such as the domains of human excretions, sexuality, and religion. As in most languages, In Spanish swearing serves several functions in discourse, as emphatic interjections expressing emotion, as expressions of interpersonal stances such as aggression or as expression of gender identity, and as forms of linguistic play.  
Spanish insults are often of a sexual nature, taking the form of implying a lack of sexual decency if the insulted person is a woman (e.g. puta, ramera "whore", perra "bitch") or implying a lack of masculinity if the insulted person is male (e.g. maricón "faggot", puto "male prostitute", cabrón "male goat/cuckold"). A particularly forceful Spanish insult is any mention of someone else's mother, (called mentar la madre), including also in its strongest form insinuations or mentions of sexual relations (e.g. chinga tu madre! "fuck your mother!").
Emphatic exclamations, not aimed to insult but to express strong emotion, often include words for sexual relations (e.g. joder "fuck!", chingados! "fuckers!") or to excretions or sexual organs (mierda!, carajo! "penis!"). Sexual taboo words that describe a masculine sexuality may be used in a positive sense (e.g. cabrón "male goat", gallo "rooster", chingón "fucker").
Pendejo (according to the Diccionario de la lengua española de la Real Academia Española, lit. "a pubic hair' is, according to the Chicano poet José Antonio Burciaga, "basically describes someone who is stupid or does something stupid." Burciaga said that the word is often used while not in polite conversation.
Burciaga said that pendejo "is probably the least offensive" of the various Spanish profanity words beginning in "p," but that calling someone a pendejo is "stronger" than calling someone estúpido. Burciaga said "Among friends it can be taken lightly, but for others it is better to be angry enough to back it up." In Mexico, "pendejo" most commonly refers to a "fool", "idiot" or "asshole". In Mexico there are many proverbs that refer to pendejos.
The modern Mexican Spanish version has different connotations depending the place or the situation, is commonly accepted as Spanish equivalent for the English profanity: motherfucker. As an adjective it is equivalent to "tough" as "It is tough" (Está cabrón). In offensive mode it means "asshole" and other insults in English. The seven-note musical flourish known as a shave and a haircut (two bits), commonly played on car horns, is associated with the seven-syllable phrase ¡Chinga tu madre, cabrón! (Fuck your mother, asshole!). Playing the jingle on a car horn can result in a hefty fine for traffic violation if done in the presence of police, or road rage if aimed at another driver or a pedestrian. In Mexico, "cabrón" refers to a man whose wife cheats on him without protest from him, or even with his encouragement.
Pinche has different meanings:
In Spain, the word refers to a kitchen helper. It mainly means a restaurant chef assistant or a kitchen helper who helps cook the food and clean the utensils. Another meaning is used as an insult, as in pinche güey ("loser"), or to describe an object of poor quality, está muy pinche ("It really sucks"). Many restaurants in Spain have the name "El Pinche", to the great amusement of Mexican and Chicano tourists.
In Mexico, the saying can range anywhere from semi-inappropriate to very offensive depending on tone and context. Furthermore, it is often equivalent to the English terms "damn", "freakin'" or "fuckin'", as in estos pinches aguacates están podridos… ("These damn avocados are rotten…"); Pinche Mario ya no ha venido… ("Freakin' Mario hasn't come yet"); or ¿¡Quieres callarte la pinche boca!? ("Would you like to shut your fuckin' mouth?"), but most likely should be translated to the euphemism "frickin'" in most situations. Therefore, it can be said in front of adults, but possibly not children, depending on one's moral compass. Sometimes pinchudo(a) is said instead. It refers to a mean-spirited person.
