The phychological aspects of language show an antithesis between learned and profane languages. The former implies control and abides by the rules of good interpersonal relationship. The latter means discontrol, violence and rupture of those rules. Profane of "forbidden" language is, always, a disturbed comunication. It shows agressive, sexual and exhibitionistic trends. It might stand for real crime at a symbolic level; and it has, in some way, a prophylactic role, fulfilling defensive needs by means of substitution. Its sexually aggressive content endangers sexual repression, therefore fostering anxiety.
