Alternate def?
diddle; verb
How about diddle as a verb meaning intercourse from the late 1960s and early 70s in New England.
Diddle meaning “to copulate or copulate with” goes back as far as 1870 for certain and perhaps as far back as 1767 in verse. It’s well-attested and included in most dictionaries, so there’s no need to include it in a dictionary of fringe English. Besides, the “diddle” on this page is just a citation: it’s not a full entry in which one would expect to include all meanings of a word.
