What does diddling mean?
Diddling is an informal noun describing two closely related kinds of behaviour: the act of cheating or swindling someone — usually out of relatively small sums — and, especially in British English, the act of wasting time on trivial or aimless activity. As a verb, 'to diddle' someone is to defraud them through trickery, as in a shopkeeper diddling customers with short measures, while 'diddling about' suggests frittering away hours instead of getting on with a task. The word carries a distinctly playful, mildly disapproving tone: it implies cunning pettiness rather than serious crime, which makes it a favourite of journalists and comedians describing minor financial misconduct. Its most celebrated association is with Jeremy Diddler, a shameless borrower in Thomas John Dibdin's 1803 comedy 'Raising the Wind', whose antics helped fix the word's swindling sense in everyday English. For anyone writing about small-scale deceit or productive procrastination, 'diddling' offers a colourful, instantly understood alternative to drier terms like fraudulence or dawdling.
The action of cheating or swindling someone; also, chiefly British, the wasting of time in trifling activity.
"The report detailed systematic diddling of elderly clients over many years."
Informal register; often used attributively in phrases like 'financial diddling'.
Present participle of 'diddle': to cheat or swindle; or, chiefly British, to waste time aimlessly.
"She accused him of diddling his business partners out of their shares."
The word 'diddle' as a term for cheating was likely popularized by 'Jeremy Diddler', a famously shameless con artist in an 1803 London stage comedy — a fictional swindler gave English one of its cheekiest words for fraud.

Etymology of diddling
The verb 'diddle' emerged in English in the late eighteenth and early nineteenth centuries, first recorded in the sense of moving quickly or restlessly before settling into its modern meaning of cheating or swindling. Its rise was greatly aided by Jeremy Diddler, the incorrigible con man of Thomas John Dibdin's 1803 play 'Raising the Wind'. The ultimate origin is uncertain, though it may be connected to dialectal verbs meaning to move unsteadily or rapidly. It should not be confused with 'didder', an older word meaning to tremble, though the two may be related.

How diddling is actually used
Informal and colloquial throughout. The swindling sense is common in both British and American English, often applied to petty rather than grand fraud. In British usage, 'diddling about' or 'diddling around' is a frequent idiom for dawdling. A further slang sense exists referring to sexual activity, which is best avoided outside clearly informal contexts.
