A greeting or exclamation used in Costa Rica with no specific definition, but means something equivalent to "ain't it great!", "life is good", "it's all good", "hakuna matata". It is synonymous with the more common expression pura vida, but is much more hip, especially when spoken by a gringo.
When a tico says "Pura vida" to you, emphatically reply "Tuanys!"
