in-law chaser
n.— «Theresa felt warmed coming inside, away from the snowy, blowing spring storm.—Theresa overhead that the storm was an in-law chaser and giggled about that. It was the middle of the night but perhaps the son-in-law ran around right now or will run around in the early morning before work check-in, chasing after the chopping of wood and gathering the food and the water and the generator gas!» —by Mary Helen Madrid-Null Navajo Heat Sept. 5, 2006.
