Hey Ammit,
Don't you mean 'numpty'? I tried the Urban dictionary, but 'nunky' doesn't exist (yet). Or is it a Weymouth term? We certainly don't use it in Lytchett.
I'm down your way on the 16th Jan to see a band playing at the Rumshack.
Best get yerself down there if you want to see something special.
