Perhaps akin to Old English dydrian, to deceive, or from variant of dialectal doodle, fool, simpleton; akin to Low German dudeldopp.
Probably alteration of dialectal didder, to quiver, tremble, from Middle English dideren, variant of daderen, doderen, perhaps from Low German.(American Heritage® Dictionary of the English Language, Fourth Edition)
From dialectal duddle, "to trick" (16th century), "to totter" (17th century); perhaps influenced by the name (which itself was probably chosen as an allusion to duddle) of the swindling character Jeremy Diddler in Kenney's Raising the Wind (1803). Meaning "to have sex with" is from the 19th century, "to masturbate" is 1950's. (Wiktionary)
