Doctrine that holds that in any movie set in the post-apocalyptic future only the most destructive products of society will survive i.e., guns, explosives, fast cars, nuclear devices, cigarettes. Common, plentiful and beneficial things (toasters, telephones, indoor plumbing) will have perished from the earth. Example: In "Waterworld," clumsy, impractical jet skis survived while millions of other boats, from dinghies to ocean liners, apparently did not.
