Like a dozen movie characters wanting a wash (5)
I believe the answer is:
dirty
'wash' is the definition.
The definition and answer can be both to do with contact as well as being verbs in their base form.
I also know that 'wash' relates to this answer.
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for dirty that I've seen before include "Obscene - unfair" , "1971 film with Clint Eastwood" , "Mucky" , "Lewd" , "Soiled" .)
