Fentanese 

When 2 or more fentanyl addicts are in their natural habitat (usually a shack) and using said fentanyl and their language suddenly becomes incoherent to the human ear BUT they all know what each other is saying without question and yet no one else but a fentanyl addict will understand

Fontanese 

The ancient language of the Fontanoza people. Once used back in 100B.C. Passed down from generation to generation, the Fontanese language lives on. Many scholars have tried to break the Fontanese code, but to no avail. Only those who have been taught this language have knowledge of its meaning and origin.

I wish I could speak Fontanese.
