<font color="green"> Only for those interested, I post these resources regarding the USA listing of obscenity (utterance = language) for the Supreme Court (non protected language) and also the DSM definition for ODD (Oppositional Defiant Disorder) in juveniles:<font color="blue">

The dispositive question is whether obscenity is utterance within the area of protected speech and press. [n8] Although this is the first time the question has been squarely presented to this Court, either under the First Amendment or under the Fourteenth Amendment, expressions found in
numerous opinions indicate that this Court has always assumed that obscenity is not protected by the freedoms of speech and press. Ex parte Jackson, 96 U.S. 727, 736-737; United States v. Chase, 135 U.S. 255, 261; Robertson v. Baldwin, 165 U.S. 275, 281; Public Clearing House v.
Coyne, 194 U.S. 497, 508; Hoke v. United States, 227 U.S. 308, 322; Near v. Minnesota, 283 U.S. 697 , 716 ; Chaplinsky v. New Hampshire, 315 U.S. 568 , 571-572 ; Hannegan v. Esquire, Inc., 327 U.S. 146, 158; Winters v. New York, 333 U.S. 507, 510; Beauharnais v. Illinois, 343 U.S. 250, 266. [n9] [p*482]

The guaranties of freedom of expression [n10] in effect in 10 of the 14 States which by 1792 had ratified the Constitution, gave no absolute protection for every utterance. Thirteen of the 14 States provided for the prosecution of libel, [n11] and all of those States made either blasphemy or profanity, or both, statutory crimes.
[n12] As early as [p*483] 1712, Massachusetts made it criminal to publish "any filthy, obscene, or profane song, pamphlet, libel or mock sermon" in imitation or mimicking of religious services. Acts and Laws of the Province of Mass. Bay, c. CV, § 8 (1712), Mass.Bay Colony Charters & Laws 399 (1814). Thus, profanity and obscenity were related offenses.

In light of this history, it is apparent that the unconditional phrasing of the First Amendment was not intended to protect every utterance. This phrasing did not prevent this Court from concluding that libelous utterances are not within the area of constitutionally protected speech. Beauharnais v. Illinois, 343 U.S. 250, 266. At the time of the adoption of the First Amendment, obscenity law was not as fully developed as libel law, but there is sufficiently contemporaneous evidence to show that obscenity, too, was outside the protection intended for speech and press. [n13] [p*484]

"ODD (oppositional defiant disorder)
The features of ODD are passive aggressive, and include a persistent argumentative nature with authority, frequent loss of temperament, frequent use of obscene language general anger, resentment, and irritability. Intentional annoyance is a common pattern, and when challenged, the oppositional blames others for the wrongdoing. The youth exhibits “normal” or “acceptable” behavior in many instances, i.e. during a clinical evaluation, an ODD youth misleads an unsuspecting therapist, or the school fails to understand a parents frustration because the youth is well behaved at school, or vise versa, the school complains to an unsuspecting parent. In short, an ODD "chooses" his or her yet, battleground. In most instances, the youth sees his or her oppositional behavior as justified, righting real or perceived injustices in its life. The behaviors are certainly annoying and trying perhaps, but fall short of physical aggression, physically violating the basic rights of others (conduct disorder)

Other features associated with ODD might include low self esteem/image, mood impairments, low frustration tolerance. Other ailments can complicate a positive diagnosis of ODD to the point where ODD is often overlooked. Such ailments include ADHD, Tourettes Syndrome (TS), and Dyslexia. These ailments can also accompany ODD, further complicating the diagnosis and proper treatment.

In My Professional Opinion:

An oppositional youth is striving to find ways to satisfy a "false" image that contradicts his or her perception of the" real" self. It can be often supported there is a deep-seated level of inward anger or sadness that represents weakness or vulnerability. The self perception of an ODD youth may also equate to that of a failure, a "misfit." It is not uncommon to find that youths with ODD also suffer from comorbid conditions that further supports a weakening self perception. In addition, many ODD youths qualify for Special Education status. Such status further supports their "misfit" perception especially as they experience the teasing and name calling from fellow students. In the end, the ODD youth is attempting to create a stronger outward image, compensating for the "flawed" real self. Such a mission creates a "split" in his or her identity (not to be confused with Dissociative Disorder, at least at this stage of development).

With such a negative self-concept, an ODD youth may choose to live up to the image, and against the real self. In the process of becoming the "image" self, they create the stranger within. They become, in a sense, a stranger to themselves. In an attempt to create a connection to this new image, they need external validation. This comes in the way of getting needs of approval, acceptance, and association met. External validation becomes to goal, the new mission. In most instances, this new mission takes the face of rebellion, of oppositional defiance. The associations made may include gangs, "undesirable" peers, illicit substance abuse/alcohol, delinquents. Students often face school suspensions, devaluing education, some might face juvenile probation or gain membership into the local juvenile institution.. Also many oppositional youth will be void of spiritual direction/training, a stable sense of a moral and ethical core.

Causes :

The causes of ODD are unclear. Studies show a variety of possibilities, Parent-Child Interaction, Family Dynamics/Functionality, Peer Sociometrics, Neighborhood and Sociocultural Factors, Bio-Genetic, Neurological Factors, etc. While researchers compile factors that might predict the onset of ODD, the progressiveness of ODD, and correlation with other disruptive behavior disorders, these same factors prove unreliable as determinates. More than likely, there is a correlation with all of these (and perhaps others unlisted) across the full ODD spectrum.

Without belaboring this point, I know of situations where ODD is present in youths where the families are relatively functional, from middle-class backgrounds, with sound support systems. I have also seen instances where functional youths come out of very dysfunctional systems, one parent in prison, or single family homes, povershed environments, etc. There are no concrete causal factors that explain a youth to go awry.

You can search online for plenty of resources for most countries around the world,and find that they generally state the same above: use of foul,/obscene language is generally attributed to deviancy/delinquency. Thus my stating that someone who uses profanity profusely is acting juvenile. sigh.
