Armoured Farmer, in reference to both the stereotype that all Cornish born men are all farmers at heart, and the Royal Armoured Corps (RAC) of the British Army. Any Cornishman that joins 2nd Royal Tank Regiment (2RTR) will be known as an 'Armoured Farmer'. This is due to the tank being a substitute for his tractor. The term is only really used in reference to any ex-3RTR and currently serving 2RTR soldiers. Officers are seen as far to educated to be considered farmers.

Adj. Something that is expected to have a long lifespan by virtue of having existed for a long time, based on the lindy effect, named for the New York restaurant Lindy's, coined by Albert Goldman and popularized by Nassim Taleb.
