A huaso (feminine huasa, although the term china is far more commonly used for his wife or sweetheart, whose dress can be seen in cueca dancing) is a Chilean countryman and skilled horseman, similar to the Argentinian gaucho and the American cowboy.
Huasos (plural) live in Chile's central valley and ride horses and typically wear a straw hat called a chupalla. They also wear a poncho called a manta or a chamanto (although this is generally reserved to land owners, as it is much more expensive) over a short Andalusian waist jacket, as well as tooled leather legging over booties with raw hide leather spur holders that sustain a beautiful long shanked spur with 4" rowels, and many other typical garments.
Huasos are an important part of Chilean folkloric culture and are a vital part of parades, fiestas, and holidays. The dancing of the cueca in which the coy china is courted by the persistent huaso, both traditionally attired, is de rigueur on such occasions.
In Chile the term huaso or ahuasado (in a huaso way) is also used disparagingly to refer to people without manners or lacking in big-city experience.
