Nickname for wild brutes? (6)
I believe the answer is:
buster
'nickname' is the definition.
(I know that Buster is a nickname)
'wild brutes?' is the wordplay.
'wild' is an anagram indicator.
'brutes' anagrammed gives 'BUSTER'.
'for' acts as a link.
(Other definitions for buster that I've seen before include "-- Keaton, US silent film actor" , "Form of address to man" , "-- Keaton, comic actor" , "- - Keaton, silent star" , "Keaton or Crabbe" .)
