A load of old cobblers

A shoemaker in 1861
Shoemaking awls

"A load of old cobblers" and variants such as "what a load of cobblers" or just "cobblers!" is British slang for "what nonsense" that is derived from the Cockney rhyming slang for "balls" (testicles) of "cobbler's awls". The phrase began to be widely used from the 1960s and is still in use but has become less offensive over time as its origins have been forgotten.
