Criminals have been referring to police as pigs since at least 1811. But just as they came up with many creative names for the people who ratted them out, crooks also called cops and private detectives by many other, more creative names. Here are a few of them from Eric Partridge’s Dictionary of the Underworld.
1. Beak Runner
A term circa 1789 for a policeman who is running down, or finding information about, criminals. It was obsolete by 1870.
According to Henry Leverage's "Dictionary of the Underworld," which appeared in a 1925 issue of Flynn's, this term referred to a detective who looked for pickpockets.
3. Elephant Ears
"Popular report has it that he listens so often, so long, so hard, that his ears grow to monstrous size," Partridge writes of this term for a policeman, which originated with a piece by J. Allen Dunn in the November 15, 1930 issue of Flynn's: "There's a couple of elephant ears ... spotting this joint."
Fuzz, referring to the police force, originated in America in 1929. A fuzzy, meanwhile, was a term from 1931 and referred to a policeman who was "very diligent in enforcing the law."
5. Lizzie Lice
A term from 1933 for policemen patrolling in cars. The singular form is Lizzie Lousie: "'A policeman who uses a smalle coupe in which to patrol his beat' ... that being a contemptuous term," Partridge writes.
This 1910 term was "not very common," according to Partridge. "Perhaps, via a hypothetical mittery ... hands clapped by policemen on malefactors' shoulders."
7. Nabbing Cull
A 1781 term for a constable or officer of the law, from Ralph Tomlinson's parody, :
”Will no blood-hunting foodpad, that hears me complain, Stop the wind of that nabbing-cull, constable Payne?”
The term was obsolete by 1860.
8. Rat Bag
An Australian term, circa the 1930s, for a plainclothes detective.
Scorch is a 1925 term meaning "to arrest (someone)." A scorcher is the policeman or detective who does the arresting.
This term for a detective comes from Edwin Pugh's 1906 novel The Spoilers:
"It shows you ain't too anxious ... to be recognised by the tiggies, see?"
It also appears again in Pugh's 1914 book The Cockney at Home: Stories and Studies of London Life and Character; by 1918, it was low slang.
11. Wire Split
This term, used since 1930, referred to a detective of the pickpocket squad.
