in-law chaser
n.— «Perhaps $714 million wouldn’t sound like a bad price if the politicians had to brave what the Navajos call an “in-law chaser” blowing snow into a virtual white-out at gusts up to 50 mph, just so their animals could drink—especially if they knew that the water they were hauling was going to freeze into ice before morning and they could count on the next day being a repeat performance.» —“Liquid of life” by Kathy Helms in Window Rock Independent (Gallup, New Mexico) Sept. 20, 2007.
