Just like every other age the Victorians had a wide variety of slang, much of which has not survived. For example:
Bang up to the Elephant
This phrase originated in London in 1882, and means “perfect, complete, unapproachable”.
Bags o’ Mystery
An 1850 term for sausages, “because no man but the maker knows what is in them”. The ‘bag’ refers to the skin in which the chopped meat is contained.
Mutton Shunter
This 1883 term for a policeman is so much better than “pig”.
