This week, Pensitivity101’s Di has decreed that D is for ‘definition’, so let’s get down to it.
Doohickey
To chew on a partner or boy/girl friend’s neck, apparently as a sign of affection, but probably with a slightly sinister proprietorial undertone. [is this still a thing?]
Donnybrook
A stream running at the bottom of the garden of one of the better known Osmond Brothers.
Dingleberry
Fruit bush found exclusively in what certainly used to be one of the less salubrious parts of Liverpool.
Dingus
An invitation to call or send a text message.
Drub
To administer a shellacking.
Dreck
A thing or occurrence that is deemed worthy of the response ‘Meh’.
Diggity
Hot stuff.
Dook
New (‘Noo’) York pronunciation of an aristocratic or royal title obtained exclusively by accident of birth rather than merit. As for the Dook of York….
Dibbly
Having the characteristics of the policeman nemesis of Top Cat.
Dinkum
A very fair question.
the only deadhead in the hameau 
Thanks for joining in. Loved #2 and ‘Dook’ and I’d forgotten Officer Dibble in Top Cat!
