in-law chaser
n.— «It was a warm summer day in June, and the sky was clear except for a small group of clouds running across the flatlands away from them, it was a quick moving summer storm. They could see the mist of rain falling to the ground below and yet all around it was clear sky. The Old man said, “There goes an in-law chaser!” The boy looked and did not know what he was talking about. “There must be someone wanting to visit somebody down there. Those kind of clouds that move fast like that they carry rain and wind.”» —“In Law Chaser” by Johnny Rustywire AllIndianz.com Forum Sept. 1, 2007. (source: Double-Tongued Dictionary)
