nicaraguanismos

links to Spanish Nicaraguan blog that is very good, IMHO...this posting talks about non-verbal communications as it is lived in Nicaragua...including the (in)famous la “guatuza”

One thing the article does not discuss is the origin of that hand movement they do where they sort of snap their fingers while doing a rapid hand/wrist action...anyone know more about that one? Sort of saying "no way" or "really, do tell!"

I think that is unique to Nicaragua.
