party-pup
n.— «Even the name we call dogs of mixed heritage has changed. When I was a young boy on the farm in southern Idaho, or first started practicing as a veterinarian, we called them Heinz 57s or mutts. Now we refer to them as canine-cocktails or party-pups.» —“Yes, multiple fathers possible within one litter” by Marty Becker News-Sentinel (Fort Wayne, Indiana) Dec.7, 2005.
