wiktionary
Originally dialectal, from Low German dudeltopf, dudeldopp(“simpleton”). Influenced by dawdle. Compare also German dudeln(“to play (the bagpipe)”).
The word doodle first appeared in the early 17th century to mean a fool or simpleton. German variants of the etymon include Dudeltopf, Dudentopf, Dudenkopf, Dude and Dödel. American English dude may be a derivation of doodle.
The meaning "fool, simpleton" is intended in the song title "Yankee Doodle", originally sung by British colonial troops prior to the American Revolutionary War. This is also the origin of the early eighteenth century verb to doodle, meaning "to swindle or to make a fool of". The modern meaning emerged in the 1930s either from this meaning or from the verb "to dawdle", which since the seventeenth century has had the meaning of wasting time or being lazy.
Extracted from Labradoodle, itself a blend of labrador and poodle
etymonline
doodle (v.)

LONGFELLOW: That's a name we made up back home for people who make foolish designs on paper when they're thinking. It's called doodling. Almost everybody's a doodler. Did you ever see a scratch pad in a telephone booth? People draw the most idiotic pictures when they're thinking. Dr. Von Holler, here, could probably think up a long name for it, because he doodles all the time.
