Bus Signs are used to inform passengers on their routes. During the 80s in Mexico as well as in many countries of Latin America, stencil bus signs were created manually with neon aerosols, which permitted people to read locations accurately. Language unifies generations as it crosses social classes in a nation. Colloquial language is never learned formally at any institution, it tends to be created within a subculture. The bus signs and colloquial language represent communication routes, they convey ideas and shake the masses, hence the slang incorporated into the bus signage.
