Used as an insult 'you doyle' also 'you doyley'
Mr OED online says,
There are no results
Lisa says, bugger.
And the OED tells me that the nearest 'alphabetical match-point' is 'doze' which is a poor substitute. It did have 'doile' and a whole load of explanation. But the word for me was d-o-y-l-e not doile.
As for 'you doyley'
Nowt there either.
It was still a useful insult to use, even if it didn't mean anything - clever really, cos if you called someone a doyle and your mam heard, you couldn't get dun off her, cos it wasn't a real word, was it?
