Etimoloxía (inglés)

Uncertain. Possibly from Latin cossus (with an additional suffix), according to the Diccionario de la lengua española of 1884, but this is highly unlikely. Possibly from a pre-Roman substrate of Iberia.
In the sense of "counter-revolutionary" or "reactionary" it can be attributed to Fidel Castro.
