denning
n.— «A biologist at the scene admitted to an independent wolf scientist that the 6-week-old pups were held down and shot in the head, one by one. This inhumane practice, known as “denning,” has been illegal for 40 years. But a simple request for information on the details of this operation, including to what extent the governor was involved in the decision, has resulted in a typical Palinesque roadblock and a string of untruths.» —“Sarah Palin: The view from Alaska” by Nick Jans in Juneau, Alaska Salon Oct. 11, 2008.

not a special word. one dictionary definition of denning is to kill a wolf inside its den. about the same act as partial birth abortion in human babies.
