Saborder: To voluntarily wrap up or destroy something. Taken in a naval context, it means to pierce a hole in a ship in order for it to sink.
As seen in: « Le leader parlementaire du Parti québécois, Stéphane Bédard, demande à l’ADQ de se saborder officiellement avant d’entreprendre les discussions sur le budget parlementaire de la CAQ. »
(Translation: “The parliamentary leader of the Parti québécois, Stéphane Bédard, is asking the ADQ to officially disband before beginning discussions on the parliamentary budget for the CAQ.”)
