Flatfoot A term with uncertain origins. Possibly related to the large amount of walking that a police officer would do; at a time when the condition flat feet became common knowledge, it was assumed that excessive walking was a major cause. Another possible origin is the army's rejection of men with flat feet, who would often take jobs in law enforcement as a backup, particularly during war when established police officers would often join up (or be forced). What is known is that by 1912, flat-footed was an insult among U.S. baseball players, used against players not "on their toes."

The term was used in the title Hot Fuzz, a 2007 police-comedy film and Peter Peachfuzz from The Adventures of Rocky and Bullwinkle. The term is also referenced in the title of the Supergrass single "Caught by the Fuzz". CB radio lingo called the police "Bears"; fuzz was a spin-off from this (this is a dubious assertion, as the term fuzz is much older than the use of mobile CB radio and older than Smokey the Bear, whose hat type, worn by many highway patrols, is the source of the bears term for police) because bears are fuzzy. In use from 1929 and of unknown origin, possibly American. G
