Maricon

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"). 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! "shit!", ¡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").

The official definition of this word in Spain is "an adult male goat".

The modern Spanish version, including Mexican Spanish, has different connotations depending on the place or situation, but is commonly accepted as the Spanish equivalent for the English profanity "motherfucker". As an adjective it is equivalent to "tough," as in, "It is tough" (Está cabrón). In offensive mode it means "asshole".

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.
