Chewbacca defense
The Chewbacca defense refers to any situation where nonsensical arguments are used to confuse the audience. More broadly, it can also refer to arguments where overwhelming quantities of data are presented as essential parts of the argument even though they are not, thus overwhelming the audience with information which cannot be successfully integrated.

Notes
Although Wikipedia claims this term originated with South Park, it seems intuitively obvious to me that it refers to the scene in the original Star Wars movie (now Star Wars IV: A New Hope) in which C3PO is playing a board game with Chewbacca. C3PO objects to Chewbacca's technique for some perfectly good reason; Chewbacca emits a classic Wookiee roar, and Han Solo advises C3PO to "let the wookiee win", further explaining that it's not a good idea to get into an argument with anyone who can rip your arms out of your sockets. The "Chewbacca defense", then, if it is partly derived from this scene, includes an element of threat due to overwhelming strength on the part of the Chewbacca defender.
