Warped eccentric wit's dry (7)
I believe the answer is:
twisted
'warped' is the definition.
(I've seen this before)
'eccentric wit's dry' is the wordplay.
'eccentric' indicates an anagram.
'dry' becomes 'ted' (to ted hay or grass is to dry it).
'wits' is an anagram of 'twis'.
'twis'+'ted'='TWISTED'
(Other definitions for twisted that I've seen before include "Tortuous - deformed" , "Emotionally unbalanced" , "Bent - perverted" , "Bent, distorted" , "Distorted; cheated" .)
