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 indigenouslanguage.
*Juan doused Maria with cold water*
Maria: Achachay, hijueputa!
Maria: Today it's 40 degrees!
Juan: Achachay! Turn on the heat.
Achacia is an awesome person. She likes to mess with people horribly but in a good way. She is funny, smart, pretty, and she is a person that really doesn't like to eat. She is also strong and fast. She loves playing in sports like basketball, soccer, softball, and football. She has many different emotions that nobody knows how she feels. If she is in a bad mood just stay away because you could trigger her. But she is the bestest person you will ever meet in your life because she is awesome in so many ways you just don't know it yet
