"Copilots" are often defined as predominately Spanish (even Catalonian) and German teens of different sexes that often hang out together.

Due to the humongous amount of time they spend together, they tend to use the same phrases at the same time. Thus, other persons that get in contact with "Copilots" mostly get irritated and feel rejected because of their parrallel speakings.

In fact, a pair of "Copilots" may seem harmless at first, but through their segregation from the society they act in the undergroundand may form a cell that is difficult to be observed.
C.: "Oh, I'm Catalonian."
F.: "Oh, I'm German."

CF.: "Let's be Copilots and make up a parrallel society! Yeah we are so cool and awful!"
