Permacrud is the irremovable layer of filth ground into the carpeting and/or floorboards of a hooptie. It is usually comprised of crumbs of food, trash, rust, dirt, mud, spilled beer, tobacco, weed, and various types of "mold". This is the layer below the beer cans, snack bags, and cigarette butts.

Permacrud is formed over a period of years, appearing as vehicle "matures" into a hooptie. It takes years of neglect, regular intervals of pressure from passengers' footwear, and exposure to seasonal temperature changes for permacrud to form.

Once formed, permacrud cannot be removed without removing the carpeting and/or floorboards.

My old lady: "EWWW it's gross!"

Me: "It's just permacrud. Get in the fucking car and and work the blinker for me would ya?"

Permaculture

The word permaculture, coined by Australians Bill Mollison and David Holmgren during the 1970s, is a portmanteau of permanent agriculture as well as permanent culture. Through a series of publications, Mollison, Holmgren and their associates documented an approach to designing human settlements, in particular the development of perennial agricultural systems that mimic the structure and interrelationship found in natural ecologies.

Permaculture design principles extend from the position that "The only ethical decision is to take responsibility for our own existence and that of our children" (Mollison, 1990). The intent was that, by rapidly training individuals in a core set of design principles, those individuals could design their own environments and build increasingly self-sufficient human settlements — ones that reduce society's reliance on industrial systems of production and distribution that Mollison identified as fundamentally and systematically destroying the Earth's ecosystems.

While originating as an agro-ecological design theory, permaculture has developed a large international following of individuals who have received training through intensive two week long 'permaculture design courses'. This 'permaculture community' continues to expand on the original teachings of Mollison and his associates, integrating a range of ideas of alternative culture, through a network of training, publications, permaculture gardens, and internet forums. In this way permaculture has become both a design system and a loosely defined philosophy or lifestyle ethic.

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
