That should get the rat scurrying.
Mafee: What the fuck is a quisling?

"Quisling" is a term originating in Norway, which is used in Scandinavian languages and in English for a person who collaborates with an enemy occupying force – or more generally as a synonym for traitor. The word originates from the surname of the Norwegian war-time leader Vidkun Quisling, who headed a domestic Nazi collaborationist regime during World War II.
