huacha
n.— Note: “Huacha” seems to be a Mexican Spanish borrowing of the English word “washer,” referring to a small, flat ring of metal. «For more than 40 years, Garcia, 66, of Las Cruces, has practiced the skill and art of huachas, also called washer tossing.…Huachas (the Spanish name for washers) is similar to the game of horseshoes. However, instead of attempting to ring a horseshoe around a stake, players try to sink a 2 1/2-inch washer into a 3- or 4-inch hole—or at least get as close as they can.» —“Tossing washers: The game of “Huachas’ is a tradition for many” by Jenn Kistler Las Cruces Sun-News (New Mexico) Sept. 28, 2007.
