tank-proofing

When you make a claim that is virtually only listing facts whilst in a debate. Origin: a tank is pieced of metal sheets that are connected to each other with studs and welding seams. The facts used as an argument in a conversation are seen as the metal studs and the welding that keep the tank together.
