You mean "doodle" as a noun, I think? It's not used to describe a person in English spoken in England. This sounds like North American slang and hopefully someone from the US or Canada can help. We use "doodle" as a verb for spontaneous and informal drawing, usually of pictures.

American English also has doodle as a verb for drawing and also for the resulting picture. I don't know of a use as an adjective in Amer English either.

lol! It was 5 months ago. I can't even remember the context. :)

In American English or British English? lol.
