otario
A gullible person or a sucker who is easily manipulated and falls for any trick. (A central term in Lunfardo, the street slang of the Rio de la Plata region, often used in tango lyrics to describe a man being fooled).
'otario, you who go around suffering without a major reason, who told you that in life everything is a lie, everything is pain?' says the tango 'Otario que andas penando' by Julio Sosa.
