cahuinero

cahuinero - a person who relates cahuínes or talks behind people's backs

cahuín - a lie that is intentionally complicated and entangled as a way to confuse the other person, and you can construct the mansa cahuín talking behind people's backs. A good piece of Chilean literature that is basically structured as el manso cahuín is Stradivarius Penitente de Alejandra Rojas. This is a very good book.

Originally I thought a cahuinero was the same as a chamullento, but they aren't. So I take that back and am going to edit the "chamullento" post.
