Překlad - Francouzsky-Anglicky - cancre/cancrerie chagrin d'école classes...

As these single words are not easily findable in any online dictionary, and are kind of idiomatic from the French scholastic vocabular (eg : "ballon prisonnier, which is a game that is plaid in the playgrounds from the school during the intercourses), translation request from these single words is accepted.
