Vicious female gets sir wound up (7)
I believe the answer is:
tigress
'vicious female' is the definition.
(female tiger)
'gets sir wound up' is the wordplay.
'wound up' indicates an anagram (letters twisted or wound into a new form).
'gets'+'sir'='getssir'
'getssir' anagrammed gives 'TIGRESS'.
(Other definitions for tigress that I've seen before include "Wild cat (female)" , "Passionate woman" , "Female wildcat" , "Ferocious female" , "Female big cat" .)
