Smooth Nick's naked and dry (6)
I believe the answer is:
ironic
'dry' is the definition.
('ironic' can be a synonym of 'dry')
'smooth nick's naked' is the wordplay.
'smooth' becomes 'iron' (I've seen this before).
'naked' says to take the centre.
The middle letters of 'nick' are 'ic'.
'iron'+'ic'='IRONIC'
'and' is the link.
(Other definitions for ironic that I've seen before include "Sarcastically humorous" , "Paradoxical or sarcastic" , "Mockingly humorous" , "Humorously sarcastic or mocking" , "Causing wry amusement through an unexpected outcome" .)
