What does diddle mean?
Diddle is an informal verb with two main uses. In its older and chiefly British sense, it means to cheat or swindle someone — often out of money — as when unscrupulous traders diddle tourists with inflated bills. In American English it commonly appears in the phrase 'diddle around,' meaning to waste time or occupy oneself aimlessly rather than doing anything useful. Both senses are colloquial and slightly playful in tone, so the word suits casual conversation and journalism more than formal prose. Its origin is obscure, though it rose to prominence in the early nineteenth century, likely helped by the popularity of 'Jeremy Diddler,' a comically shameless borrower in an 1803 stage comedy whose name seemed to capture the art of getting money by trickery. A person who habitually cheats others may be called a 'diddler.' The word's bouncy sound and mild sting have kept it in steady use for two centuries.
To cheat or swindle someone out of money or something valuable.
"Unscrupulous mechanics diddled customers into paying for repairs their cars never needed."
(Informal, chiefly US, with 'around') To waste time or engage in aimless, unproductive activity.
"He spent the afternoon diddling around in the garage instead of mowing the lawn."
A famous 19th-century stage con artist named 'Jeremy Diddler' was so memorable that his surname may have become the English word for cheating people altogether.

Etymology of diddle
The verb diddle first appears in the early nineteenth century meaning to cheat or swindle, though its ultimate origin is uncertain. It is often linked to 'Jeremy Diddler,' the endearing con man in James Kenney's 1803 comedy 'Raising the Wind,' whose popularity likely cemented the word in everyday speech; some earlier attestations exist, so the play probably popularized rather than coined it. The later American sense of wasting time developed separately in the nineteenth century.

How diddle is actually used
Both senses are informal and carry a slightly comic or colloquial tone, making them unsuitable for formal writing. The swindling sense is more common in British English; the time-wasting sense is chiefly American and usually appears in the phrasal form 'diddle around.' The word is mildly pejorative but not obscene.
