In the mini series Sherlock the character by the same name referred to his mind as a castle. a castle that he would figuratively travel through. Each room was filled with
knowledge that he had stored away for him to easily relocate in a time of need.
A Mind Doublewide is the poor
white trash version of that. It is a repository of usless
information mainly comprised of Pro Wrestling knowledge, 1980's action movie quotes, blist actor names, ways to work over the government, and dead cats. lots of dead cats.
