An Ecuadorean expression used to denote extreme cold, just as English speakers say "brrr". It's meant as an onomatopoiea for chattering teeth. Comes from the Quichua indigenous language.
*Juan doused Maria with cold water*
Maria: Achachay, hijueputa!
Maria: Today it's 40 degrees!
Juan: Achachay! Turn on the heat.
