Abstract This reflection considers asks of the practices deviating with adolescence in the plans of the clinical approach and theoretical reading. The complexity of the behavioural productions in the field of youth reveals, at the same time, the problems of adaptive rules, whose failures was attested on the register of many psychopathological formulations, as well as the limits of a coexistence based on antagonistic emotions. The teenagers, then, are been confronted with the unrealism of their phantasms. They are also introduced to the rigidity of the social and cultural forms and policies of their environment. The instability of the moderating or integrating referents of the institutional, family and psychosocial areas confers the search for discharge system meant in the expression of marginal rites and the development of peripheral places, symbolic systems of cohesive membership and singular identity.
